Right...  Square A and Square B *are* the same colour.

If you cover the screen with your hands so you can only see a very narrow vertical slit, you can see this is the case, although it does mess with your head somewhat.  It also results in greasy fingermarks on your screen.

Weird, isn't it?

lowey:
If grey is a colour and A & B are shades of grey on the same 2 dimensional image taken in isolation then yes they are the same colour. :-s

However, if the whole image is taken as a 3 dimensional image with the representation of light casting a shadow past the vertical solid cylindrical object then the representational notional colours are still grey, but one "B" light grey in shadow and the other "A" dark grey fully illiminated.

So if A is grey & B is grey irrespective of shading or shadow effects then they are both grey & hence the same colour. #-o

My brain has just exploded , i will have to take a tablet ArGHHHH! ](*,)

POTASH:
