    Since I didn’t believe you, I had to take the graphic in my own program and check it. It is the same color even though I still find it hard to believe.

    how is it the same color? is it the shadow or something else that gives the illusion of the different shade?

    IF THEY ARE OF THE SAME COLOR, THEN THE CHECKER PATTERN WOULD NOT EXIST. ARE WE NOT LOOKING AT A CHECKER PATERN? EXPLAIN PLEASE.

    Its simple enough people. the cylinders shadow darkens a portion of blocks making it hard for us to determine what color they should be. Our brains automatically assume the block is lighter due to the position of it in the pattern.
