A different take on the "Save For Web" color shift issue...

Question

Ok, everyone who has fussed much with photoshop and "Save For Web" knows about the color shift issue. If you want your colors to look right after you "save for web", you have to work in the sRGB colorspace, and have Proof Colors checked (soft proofing on) and the proof color setup set to Monitor RGB, otherwise what you get looks terrible when displayed in a browser.
But of course if you are editing for print, this is exactly what you DON'T want to do. Well, I work in both. In fact, often the same images, and I want them to appear as close as reasonably possible in both print and web formats, and without a lot of fussing on my part. And I'm pickiest about the print mode, since I have the most control there, so that's the way I want to edit by default.
Nothing new here.
Now comes the interesting part (in my mind, anyway). Obviously there is a known remapping -- because PhotoShop DOES it when you select Proof Colors. So the inverse mapping must also be known (with some gamut issues, but I'm not concerned with those, because, after all, I'm VIEWING it on a monitor anyway!). What I want is a plug-in that automatically applies that inverse mapping so that, when I do a Save For Web, I end up with the colors I've been viewing all the time when setting the shot up in print mode. Then, too, I don't have to worry about what mode I'm in when I'm editing -- it just fixes it when doing a save-for-web.
Again, I want to edit in my normal print mode (typically ProPhoto colorspace, and with soft-proofing off or set to the printer/medium combination I expect to use), then do a single operation (might be a multi-step action) to "screw up" my colors so that when I then do a "Save-For-Web", the resulting image, when viewed on the average color-stupid browser, looks like the image I've been seeing in Photoshop.
Anyone know of such a beast?   I would gladly pay for a plug-in that really works and fixes the problem.
And if you have other solutions, I'm interested, but the absolute requirement is that it I do one single edit pass for my colors for both print and web use, and I get what I see on the screen in PS on both the prints and on the web display (i.e., working in sRGB/Monitor RGB mode all the time won't cut it). And PREFERABLY, let me do all my editing work in the ProPhoto (or at least AdobeRGB) colorspace so I have a gamut closer to what the printer can do.
Anyone got a decent solution for this?

Answer 1

Sorry, I think I'm being unclear.  This has nothing to do with individual monitor profiles.  In Proof Setup, "Monitor RGB" amounts to turning off ALL color management, and simply letting the monitor do what it will.  It is what the vast majority of web browsers do (even if the operating system provides color management, the browsers don't take advantage of it), so that is what you need to consider for images that will be viewed on a web browser.  If you convert your image to sRGB,  select Monitor RGB in Proof Set up, and turn on Proof Colors, you will see the image as it would appear on a web browser (after you save it as a jpg or use "Save For Web/Devices" to save it as a jpg).   Since almost everyone is running different uncalibrated monitors, there will be lots of variation in how it will look to them, so precise control of the color is unimportant.
That said, I would expect the color on a calibrated monitor (such as the one I use when editing) to be reasonably close to the colors I am seeing while editing in PS.  To the extent a monitor deviates from "calibrated", those colors will vary, but a good monitor should show good colors.   Unfortunately, this is NOT the case, as my previous post shows.  The colors produced by the steps above are oversaturated and significantly shifted in hue.  There is, to my mind, anyway, no reason for this.  Adobe clearly knows what the mapping is between the colors as it displays them in PS and the un-controlled "Monitor RGB" -- that is, it is the color map they are using during normal editing display.  If they were to reverse-apply that map prior to saving it as a jpg, then the image would appear on a browser on that same (presumably calibrated) monitor very similar to what you set up when editing.  Anyone else viewing the image on a web browser with a calibrated monitor would also see good colors.  To the extent other viewers' monitors are out of calibration, their colors will suck, but there's nothing you can do about that.
I guess in some sense I AM "asking for a Color-Mamangement-solution for a "non-Color-Management-situation", but specifically I'm asking for PS Color Management to do the best it can for non-Color-Managed situations that we all face every day.
Does that make more sense?
