>>8053393The problem isn't red + blue per se, it's that mixing bright colors like that makes it look like a toy for special needs children. Using dark colors already looks better. And making one dark and the other light looks excellent, see how good dark red + trans medium blue looks here.
Also, that MOC lacks black accents that tone down the brightness, which is the problem that STARS Tahu had and that made him look so bad compared to OG Tahu Mata.
