From what I've read, yeah, Midnight Blue would have the same issue. The "issue" is using non-white plaster in the cement mix. Having a pigmented cement mixed with the aggregate makes it more challenging to retain the appearance of the DB finish, and flaws can be more noticeable. I liked Tahoe Blue, too, and was thinking that would be the color I'd choose, but 1) it was an DB "upgrade", and 2) I didn't want more trouble with my DB finish than what I was already going to get. This is, afterall, my first pool, so I didn't want to be more ambitious than what was warranted.

Also, with the darker pigments, be aware that they'd make your pool water warmer. I live in So. Fla., and I don't need my pool water to be any warmer than it already is right now -- that is, between 89 and 90 degrees. Not sure where you live and whether that would be a consideration to ponder over, but I did ponder over that matter before selecting a DB finish.
