How about subtracting colors instead?

Like...

Or maybe subtracting colors, but the lower user right's color is halved, since I realized that the colors are just too dark using the above example.

If the color result is in decimal, then it's rounded down. Pick the color that has a greater color value for the first constant (constant a).

Formula: (a - (b / 2)) = c

That's what I can suggest now.
