tell me i’m not insane rubik’s cubes used to have black rather than blue right?
As in what? There are three things I could interpret this as:
The colors you use for solving (in which case I don’t think so)
For a stickered cube, the colors behind the stickers (in which case absolutely)
For a stickerless cube, the colors “in between” (no clue how to word it) the pieces (in which case idk)
the 1st one;
my father had an old stickered rubik’s cube that had black plastic behind the stickers but also black stickers on the side opposite green
