You might not believe this, but the A and B tiles in this image are of the same color.

Humans' recognition of color is vague like that, you know? So your black could actually be a white, you know?

I see! So you're saying that I shouldn't be fooled by appearances, but instead, look for what truly lies in one heart, right!?

Thank you, I learned a lot from that! I will restate my verdict!
