I think the D-Theme is special enough that it won't look like a copy of marina just because you use similar colors.

I must admit that I like the blue versions of D-Theme most but for my taste it is a bit too blue. That's why I am asking for a mix of black and blue. Some sort of "D-Theme AeroElegant" should come out of it.

But maybe you have your own idea of what would be an elegant version of Aero?
