Convert RGB to HSV

[Randall Reetz]

Just thinking... but by light mixing physics it would seem that Hue would simply be some three-matrix sum, S would be the sum of R,G, and B devided by the range for any one of them, and V just that total range minus S.   Is all of this "min" and "max" just some sort of maths shortcut?  Maybe this is a way of figuring the range between R,G, and B?  Seems unintuitive as it obfuscates the real relationships involved.  What am i missing?

Well, well, well . . . digging around in the Documentation I discovered

statRound (having fallen foul of 'round');

still feeling a bit 'funny' about those negative S values . . .
