Their colors are more based on their appearance than their magic. That being said, it's hard to say not knowing which direction the light novel will go with them. The WN more focuses on their Ultimate Skills, Nuclear Strike Magic (the strongest class of magic), and magical weaponry. However, Diablo, Black Progenitor, is noted by Rimuru to possess Dark Magic, so you are on point at least with him. Guy, Red Progenitor, also uses fire/heat explosion-type magic is the form of his Napalm Blast magic, so he has Fire Magic as well.
