Randomized Colors are Too Dark. Questions on Color Boxes

Question

Hey all,
I am attempting to change the color of the plots on a mixed signal
graph remotely using the "color box" control which works fine; however, I
am also setting the color boxes to a random color when the program
first starts up which is where my problem lies.
What I currently am doing is that I have a random number generator
pumping out a number after which I multiply the number by 10000000, just
to give me some colors brighter than black, and then I have that wired up to
the color box control I am setting the random color on. The problem with
this is that although it does produce some decent colors some of the
colors produced are quite dark and pretty hard to see on the mixed
signal graph.
I could make the graph background a different color if I have to in
order to see a majority of the colors that come out, but I would much
rather just have the colors come out more on the bright and colorful
side.
So I have two questions for you guys and gals:
1) How do the colors of the colorbox get determined using the unsigned 32 int?
One such example of why I am confused is that the number that I have
going in is 5726420 from the random number generator (+ being
multiplied), but on the colorbox control the RGB value is R:87 G:96
B:212. Why is that?
2) Is there any kind of algorithm out there that someone has done
that can produce values randomly that will give kind of neony colors? or
anything semi-bright for that matter?
Any help is very much appreciated!

Answer 1

Use "RGB to color" from three random U8 (o..255) values to generate a color. (double click it to open the VI to understand the structure of the color data type )
