  Internal color calculation should always be done in floating point, unless for realtime purposes. Usually channels (regardless of the color model) are considered to range from 0 to 1 (exception: YCC, where chroma is -.5 to .5). Only when performing the actual drawing, the float colors are scaled into the target image's color format. That way you would not have the problem, and also minimize...

  CW or CCW depends a little on how you draw the color circle. The mathematical positive direction is CCW, which also seems to be the common way to draw it. To make it CW, you can just flip the two colors and reverse the generated gradient :)
  
  
  The multicolor thingy is something quite different: It's for when you want to blend between two colors, but need to define a specific color that should...

  I just saw, that my HSL idea could still work, since you made an error in your example:
  
  RGB(255, 0, 0) = HSL(0, 100, 50)
  RGB(255, 0, 255) = HSL(300, 100, 50)
  add H/S/L values and divide by 2 you forgot the latter ;)
  result HSL(300150, 200100, 10050) = I don't have a converter handy, but I am pretty confident, that this will look a lot more like what you want

  Well, there is a multitude of possible ways to tweak this. And since we do not know where your sample came from, if you need to reproduce it exactly and how your original reference actually does it, we can merely try and try and try to get closer to it step by step. With only one sample and no way to see what other border colors should produce, this is as far as it gets - at least if we exclude...

  Ah! You don't want to blend with multiple preset colors in between, but using a different color model I suppose! The above looks like the blending was done in HSV or HSL space. (Don't know if right- or left-handed hue, but that should be simple enough to try out.) So instead of blending using RGB, just do it in HSV/HSL. That should get you pretty close to the above result.

  He means that you simply need to string pairwise blended colors together. That's the common way of doing it, and most probably also the by far easiest, especially if you have gradients for two colors already implemented (since it's the same thing, just done a few times in a row).
