Substrate and lighting play a big part. Plus the individual fish patterns.
I dont see much grey in koloton and think that they have crisper patterns. But could be wrong. I hate comparing fish with pics on the net and dont know if this goes for all koloton/nigerian but i think the kolotons pattern get checkered towards the tail almoat like ansorgii and the nigerian is wavey. lol but thats what my eyes see. Both are really nice fish.
Kolotons
