is there any way to take into account the two parent colors and breed some sort of mixture color for the foal?
how are you deciding the foals color?
Do a for loop for R, G, and B.
Get the R/G/B of both the mother and the father, determine the lowest and the highest.
New R/G/B is ( (highest - lowest) / 2 ) + lowest;
Combine the three new colors into the result.
This add-on will eventually be released, btw.
