The dark blue combo color clearly violates the rules.No.
There was a topic about combo colors saying that rules should be added in ranking criteria for black and white combo being hard to read (I disagree with white lol) but anyway, it got denied. So even there your dark blue color is out of subject. I agree it can look a bit odd at first sight on 100% dim but it's totally readable and if I personally disagree with it I can just put my own skin combo.
Anyway, what we're saying is that it's a minor thing and doesn't warrant a (last minute) DQ. I mean, the topic cleary shows that nobody cares of it.
