IMO the too-dark issue is not about function. Of course you can tell them apart.
Rather it's a question of aesthetics. If I have a large pot of 100s with a few 500s tossed in, I'd like the 500s to "pop". (Remember the "pop" we were all looking for earlier in the process?

). Same with stacks of 100s and 500s; I'd like the 500s to have more contrast and stand out more.
That said, I do really like the spots on JMs chip and will probably vote for it right up through the semifinals. I just wish the base color was one of the lighter shades.
Or maybe we could break tradition and move this chip to the 1000....
