I once took yellow stickers off of a black cube to make it a black side. Horrible failure. It's very hard to recognize with the black.
But maybe that only was because it was a black cube. If it's white, i think it'll be alright.
when you have instead of white stickers black it is not so bad but the cube looks much better with white stickers. Black may be only a little confusing, with the blue color!
I use black instead of white and that's REALLY COOL! But my friend uses black instead of red Totally crap! If I want to solve it I have to look every time three times the black face and think: what the f**k? I think black is very cool but it should be on right color.
My white cube has white stickers. But when I got the cube, I thought the black was so cool looking that i replaced my least favorite orange with it. but **** the black-blue recognition sometimes tricks me.
