Hola!
I hope you (or anybody else) can help me. I have a similar problem though I only confuse red and green. The problem is that my cross is blue, so my top layer is green, and when in F2L i sometimes put in the green-yellow edge instead of the red-yellow edge. Also in OLL i sometimes get confused. I was thinking in changing green to black, but i have no black stickers and I was wondering if changing to the japanase color scheme would be ok.
I hope you can help me.
Greetings.
