Color test

Hoonius was right.

As it happens, B is darker because of the way the squares merge with surrounding squares and the fact surrounding squares of B are darker than the squares surrounding A. Whilst the colour is identical in the centre of squares, the average across both squares puts B darker due to said merging between squares.

Do I get a medal for going too much into it and somewhat proving the expected answer wrong ?

No cause your wrong..the squares are 100% the same color on the whole
