Here's a developement. I was documenting the different values of temp_pixel.blue based on the different colors it was reading, and here were my results:

red = 62;
orange = 63.156;
yellow = 63.969;
green = 1.969;
blue = .030;
purple = 62.030;
white = 63.999;

The interesting thing about these findings is that red, green, and blue have their own set values, while the yellow, purple and white are all just the sum of the red, green, and blue values (ex. red = 62, green = 1.969, yellow = 62 + 1.969 = 63.969). Orange is a little different because I made it 255 red and only 75 green. I don't know what this means, but I thought it might be important.
