Colors are funny things to work with mathematically. The main thing you need to keep in mind is that you have to treat colors as THREE numbers, not just ONE.
It's worth remembering that there are different ways to represent colour: the way you are describing is the RGB colour space, and should be treated as 3 separate numbers for (hopefully) obvious reasons. If you use the HSV (Hue, Saturation, Value: https://en.wikipedia.org/wiki/HSV_color_space) colour space then it is reasonable to fix the saturations and values and choose equidistant values for the hue.
Well I guess this almost Finalizes my next build sorry AMD looks like I am going with intel .. that on-board GPU does what I need ( VA API)
and runs doom3 as a bonus to boot
which means any game I would play .. should work ( UT2004 ect )
but I will still wait for AMD A10-5800K release .. but it doesn't look good for AMD with their driver support
I hope their will be another good linux test i7-3770K vs A10-5800K
looking for lowest power with full support as HTPC
