As many of you who own a square-2 may know, with the split corners comes allowance to fully switch the top and bottom layer in such a way that all sides remain solved.

Since the layers can be switched and the puzzle will remain in a solved state, what would you define as the solved state for the square-2?

Is it limited to the original color scheme, or are both solutions valid?

Both solutions are valid, but for me my solved state would have to have yellow on top.
