Actionscript 3.0 Color Interpolation Question
In Actionscript 3.0, the Color class has a method called interpolateColor. It seems strange to me, but the method takes two unsigned integers for the colors as opposed to two instances of Color. Additionally, it returns an unsigned integer for the resultant color. Anyhow, I don't see anything in the API for converting a Color to an un...
Is there an algorithm for color mixing that works like mixing real colors?
The common mixing of RGB colors is very different from mixing colors for paintings, it's mixing of light instead mixing of pigments. For example: Blue (0,0,255) + Yellow (255,255,0) = Grey (128,128,128) (It should be Blue + Yellow = Green) Is there any known algorithm for color mixing that works like mixing real colors? I've alread...

However, I can change the text color: $('input').css('color', '#f00'); I've tried this in both Safari 4 and Firefox 3.5 with the ...

Iterating over colors
Is there a good way to iterate over colors? I know it sounds like a strange question but here's an analogy. Suppose you write a game where you travel around the Earth. You pick a starting point and then you define a rule that you apply repeatedly. For example: Start at your current location on Earth and then define the great circle ...

Color Interpolation
Okay, so I'm looking at a typical color chooser and it looks something like this: If we deal with only highly saturated colors, the blending pattern behaves like this: R 255 G 0 B 0 R 255 G 0 -> 255 B 0 R 255 G 255 B 0 R 255 -> 0 G 255 B 0 R 0 G 255 B 0 R 0 G 255 B 0 -> 255 R 0 G 255 B 255 R 0 G 255 -> 0 B 255 ...
