Yes, personally I think they are pretty pointless.

They're describing things that are already clear and that people don't need to be reminded of. The colour of a character (perhaps excluding the coloures from this point since that's their main trait) isn't any information that actually matters.

I do believe Jordan made them just to get points to be ahead of everyone. Considering the other things he's done in the past I would certainly not put it ahead of him.
