No color on my computer

The color pops in and out of my imac. any ideas on how to fix it.

Hi,Welcome to Apple Discussions.
I'm afraid you're going to have to be more specific!
Is the coloured casing popping off the iMac?
Is the iMac showing a black and white display only?
Do the colours fade in and out on your computer?
If you hook up an external display do you get the same effect?
What type of iMac do you have? (iMac G3 (CRT) / iMac G4 (angle poise Flat Panel) / iMac G5/ICD )
When does the issue occur? All the time, when you do something particular or randomly?
Have you tried adjusting the settings in Apple Menu > System Preferences > Displays ?
cheers

It's easy to revert back if you have a backup of your system.
If not, the doing is much more complicated and tedious.
It would help us to help you if we could have some more technical info about your iMac.

Change the colors in my computer

hello . can you help me ! .. i shooting by canon 6d and when i open my photos in my computer i lose my colors .. and BTW i using RAW and i tried lightroom in Digital Photo Professional and all is the same thing and i do not why ! >> what is wrong with my computer ?? and how i fix it .

I would think ACR would give you color where DPP may give you BW if you have set your 6D to BW. RAW files do not contain a color RGB image they contain luminosity values for each pixel and each pixel has a filter in front of it which is Red, Green or Blue. There are twice as name green filters as there are red and blue filters. You should always be able to convert a sensors RAW data into an RGB image. If you can upload a RAW file and post a link to it so we can see that there...

Spinning color wheel whenever computer is used after idle for a few minutes

Whenever I try to use my iMac after it's been idle for a few minutes there is a 3-5 second delay while the color wheel spins. This happens in all programs. I have deleted the plist power settings and all sleep options and processor options have been tried to no avail. The mouse remains responsive and I can move the cursor but whenever I click or try to execute any operations the color wheel appears.
Any suggestions would be greatly appreciated. Thanks
iMac G5 rev B Mac OS X (10.4.4)

Thanks, but no Norton installed. It gets a little stranger; I reinstalled the system software with an archive and save. Now I still get the delay after the computer is idle for a few minutes, but I no longer get the color wheel. Example, if I start iTunes and then wait about 2-3 minutes when I hit play the play button turns blue but it takes several seconds before the song plays. Before I reinstalled I would have the same delay only I would get the color wheel.

Cannot print in color from my computer

ENVY 7640 all-in-one. Brand new. Using the cartidges that came with the printer and ink levels are fine. Running Yosemite on my iMac. Using wireless connection. When I set this printer up last week, it printed in color including from my computer, iPhone and iPad. But starting Friday night my screenprints from the computer have only come out in black and white. Checked the cartidges. Ran a print check--which came out in color. Checked printer settings on my Mac: they are set for color, not black and white. I still have my old HP 4700 printer hooked up and that will print in color. Could sure use some concrete help. Thanks.

Background color differs from computer to computer

1. I have a page where users can enter some data, some of the fields have back ground color YELLOW on SOME computers (same browser version IE 7...) ,I never seen it on my desktop and some others but I see it on few others.
2. some of the text looked BOLD on some computers.
What could be the reason?
3. some of the buttons seems to be diff than other, Image vs HTML buttons , I saw the threads talk about "rebooting display server". what is display server. I reboot apache but nothing changes. what is display server?

Display server is X.11 server, different from Apache, ask your DBA for bouncing this

Is Apple's Color Compatible With My Computer?

I have a G5 . . . however, it's an older Dual 2G G5 with PCI-33 slots . . . These slots will not allow me to work w/HD material because they're not compatible w/any HD cards, etc . . . I have FCS, but am thinking about upping to FCS2 - particularly to use Color. Would I be able to use Color on this computer then?
Also:
I have a Sony DVMC-DA2 analogue to digital media converter that I use to view FCP footage (DV) externally on a monitor. I believe I recall hearing or reading somewhere that Color may not be compatible with this device and I would not be able to view my footage externally using Color and my media converter.
Is any (or all) of this correct?
One last thing: If I CAN'T use this particular G5 set up as it is with Color, would the purchase of a Matrox MXO that takes the video and audio information directly from the computers DVI slots for the purposes of transmitting "accurate color" to a 23" Apple Cinema Display, somehow, circumvent whatever PCI33G5-to-FCS2's-Color incompatibility issues there might be?
Thank you all in advance for helping out and answering these, possibly confusing, questions. I'm just trying to figure out the best setup that I can get to configure my computer to color correct my present project (a DV feature) as well as future film and HD projects.
Thanks again,
Javier Calderon

Just did a search and found info that . . . well . . . although helpful, wasn't too promising for my particular "iron".
Zebulun wrote:
"Well, you can waste a lot of time and money trying to get your old iron up to speed but the sad fact is, even though it may work with Color, it will most likely end in a less than satisfactory experience all around. You need to determine if your G5 has PCI, PCI-x or PCIe slots and then purchase the appropriate cards.
However, Final Cut Studio 2 is optimized for the Intel processors. You will see users here and there using the newest models G5 with great success but quite honestly, you need a Mac Pro."
Although not specifically stated, the verdic doesn't look good at all for my "paltry" PCI33s . . .

Computer color isn't right after pluggnig printer in.

I took my computer to get a virus out and it worked fine.
I had to reinstall my printer but plugged the printer into the computer before I loaded the sofeware.
Now the color on the computer is wrong...acts as if there is no red.....plus it won't let me install the sotware for the printer.
I have tried system restore but that didn't work.
Is there anything I can do?

Hi,
The printer more likely will not cause a such.
Try removing and re-plugging the display cable from both ends, I assume you might wrongly loosed the display cable while connnecting the printer.
Run the installation again and only connect the printer once the installation as you to, if ther is still no response click on Start, then right click on My Computer and select Manage.
From the left pane click on Device Manager.
Double click to expend the Universal Serial Bus Controller categoty.
Locate the USB Composite Device, right click it and select Uninstall
Note: if there are several you may remove them, those will be redetected automatically.
Next right click on Universal Serial Bus Controller categoty and select "Scan for hardware changes".
The software installation should now proceed further.
Hope that helps,

HP Envy 5530 won't print in color from Mac

My printer won't print anything in color from my Mac. I've tried printing from Word and from a PDF, and each time only black ink will show up. I've tried:Removing the black ink catridge and printing with just colorShaking the color ink cartridgeRemoving and putting back the color ink cartridgePrinting a test page (color doesn't work for this, either- nothing prints at all when I do this)Double and triple checking my print settings The only ink color that my computer says is "low" is yellow. I'm printing wirelessly, but because black ink prints fine, I'm willing to bet there's no connection problems. DO NOT try to sell me more ink; I am already upset with HP enough as it is. The last thing I want to do right now is buy more of its ineffective products. Please help me fix this problem.
Thank yoooouuuuu

Hey , Welcome to the HP forums! I hope you enjoy your stay here. I see that you are having issues with printing in colour from your Mac to your Envy 5530. I can help with that. To start, this document outlines how to troubleshoot print quality issues with your printer. When you get to the Solutions that suggest replacing the cartridges you can instead click on this link to contact HP Support. On this page if you scroll down and fill out the form you will find their contact number. I will warn you that if the cartridge is showing as low their solution may be to replace the cartridge with a new cartridge. I hope this helps and I hope you have a great day!

HP Color Laserjet 2500 printer

I have a HP 2500 Color laserjet printer that will not print in color. New color cartridges, will do color for a test page, worked fine with Win XP, new HP computer with Win 7 and it will not print in color from the computer. Think I have the right drivers - PCL5 ver 5.1.1.8283 - PCL6 v. 5.1.1.8283 - ver 5.0.3 PCL 5 & 6. This is a great color printer and I just spent a lot of money for new color cartridges.

Hello Bambi:
You can ignore those permission repair messages. Everyone gets them, and they are "informational" - to whom, I do not know. FWIW, permission repair is, IMHO, a waste of time (although I do it myself after a software update).
Try deleting the printer and then reinstalling it.
Has anything changed before the problem began?
The "ton" of firewall messages may or may not be relevant.
Unfortunately, I do not use a wireless network (mine is Ethernet). There is a rather large HP driver update that Apple released a couple of months ago.
As a further suggestion, you might post your question in the networking forum. I am not (to say the least) expert in connectivity problems, but people there have a lot of expertise.

How do I calibrate the monitor to the printed photo for equal color tone and brightness?

Where in the program do I calibrate the monitor color to the resulting printed color. My printed photo is much duller and "blacker" than the monitor. Other color programs has a setup section to plug in the monitor's ICC profile along with the printer used so the resulting printed photo is very close to your adjusted photo on the monitor.

I just got my laptop and I'm a photographer. It is very important to get my laptop similar in color to my photos. So when they are printed they look similar to most basic commercial printer (Walgreens etc) I had no problem on my old computer. My Satellite seems very bright and the people looked washed out. I used th ctrl, alt f12 key and there was a contrast adjustment. I just can't seem to get a nice natural color from the computer. Can someone let me know what they use or what looks good to them. The factory default seems way to bright and people look to bright?? Thanks so much in advance...

Not printing in color at all...

I am a teacher and have been trying to print in color on my printer and everything is coming out in black and white. I have already changed the toner cartidges and ran test pages and "cleaned" it. Each color cartidge is showing at 100% but no matter what setting I play with, it won't print in color. Please let me know how I can fix this. Thanks so much for your help!

Hi @uniquekds ,
I see that you are having issues printing in color from the computer. I would really like to be able to help you resolve this issue, but I will need some more information.
I am assuming you were able to print the Supply Status page in color then, is that correct?
It is just from the computer, that you are unable to print in color.
You can try these steps to make sure the grayscale isn't selected in the print driver. Depending on which model that you have it may be a little different.
1.From the software program, select the Print option.
2. Select the product, and then click the Properties or Preferences button.
3. Click the Color tab.
4. Click the Automatic setting.
5. Make sure that Print in Grayscale option is unchecked.
6. Click the OK button.
Download and run the Print and Scan Doctor. It will diagnose the issue and might automatically resolve it. http://www.hp.com/go/tools>Using HP Diagnostic Tools for HP Printers in Windows.

What were the results when you ran the Print and Scan Doctor? (did it print or scan, any error messages)
If there is anything else I can help you with, just let me know.
Have a nice day!

Why CMYK Color Profiles Warning?

Hi guys,
I just made a couple of CMYK shades of grey. Here is a sample:
http://www.pixentral.com/show.php?picture=1fo01uualiQLkc4uuLbXfnAoWsiVw
When i export the PDF to High Quality Printing, i get Warning Icon with the message "The preset specifies source profiles that don’t match the current color settings file. Profiles specified by the current color setting will be used" Why do i get that message? i am not using or importing any Photoshop Image with a different color profile...i just created my CMYK color inside my document.
I am sending this PDF to a Laser Color CMYK Printer (not my own home laser printer) something like a Kinkos Store. Could that be a problem for color settings to a this kind of printers? By the way, these are my color profiles.
http://www.pixentral.com/show.php?picture=1EEuCxcbSjWaY2cNQj8dBAFedNlly0
is in Spanish but i think i quite clear.
Thanks for any info on that!
Cheers,

I'm here because I was researching the same error. I've gotten it for years, and usually worked around it but finally got around to trying to get to the bottom of it. One thing I just noticed is that I had a file where I received this warning, and then went to Edit > Convert to profile in ID. I noticed that the Source of the file was NOT the working space set in my color settings (different computer from where I created it). I converted the file to the working space profile, and went back to Export to PDF again, and DID NOT get the warning.
My concern would be what ID does if you ignore the warning. If my profile was different from teh working profile and I go ahead and covert anyway, will ID ASSIGN the working profile to my file, or CONVERT my images to the working profile specified in the color settings file. Which it chooses will likely have an inpact on my color. I might try to test this by creating an image in a wierd source profile that will look quite different if the numbers are just ASSIGNED a new profile and Export to PDF and see what happens. I think that might tell me what ID is doing.
I really would like to understand this for certain.

No color on my computer
