Here is a scan of the blocks from the lot (the singles are far too numerous and disorganized). The blocks that jumped out to me are the block of 15 2nd from the top, and the block of 6 at the far right. They are both brighter than the others, yet different from one another.
Obviously, given the tolerances in scanner, web browsers, and monitors exact coloration cannot be conveyed, but you can see the comparative differences.
