At first it does, but after a while you just see it without thinking or checking. It's hard to describe, but when solving I see different "weights" of colours between those cases, rather than specifically thinking about which colour is where. So A and T have a single strong colour but G and R have a second strong colour that also stands out.I'm having trouble differentiating between R perm and T perm as well as A perm from G perm from this angle.
I mean, it takes a long time to check whether you can see all 4 colors or not.
