I happen to know one gene critical to producing blue pigment in the blue parent variety is temperature-sensitive, leading to brown pigment when it is relatively warm/hot out.

I was only able to figure this out from several years of observation, but one could grow plants at different temperatures in growth chambers to figure it out in about a year.
