In the process of creating an Icon object, I need to reduce the numbers of colors in an image from thousands down to 256 or less. I do this by "chromatizing" the RGB values - counting the colors - then re-iterating the process with heavier "chromatization" until the number of colors is reduced to my requirement.
I searched these forums and google on this subject to find out more - but I found that I alone call this process "chromatization" it seems. So I was hoping someone could help me out with the correct terminology.
Specifically, I want to use the correct terminology on my UI buttons (at present I have a button labeled [Chromatize] . .) and I am curious as to whether it would be good practice to "chromatize" the Green most heavily, the Red more moderately, and the Blue least . . . or just "chromatize" them all equally which is what I have been doing

What I've got so far, is as follows: The user is presented with 3 sliders (one each for R, G and B) and a button. The 3 sliders each go from 0 to 15 - and when the user hits the "Show me!" button, Select Case jobbies translate the 0 to 15 values as seen here:

I am working on a program to generate 50 circles starting with the smallest in the center of the form. The circles do not over lap and the appear to grow outward. Each circle has to be a random color. I have the code that generates what I need but all the circles are the same color. I was thinking about either using an array to hold each circle and color as to not assign the same color to all of them but not sure about putting a graphic in an array. I also think maybe a nested loop of some sort but was unable to figure one out.
