The Zircher-UDON (I believe it was M3th) collaboration who did the Cable&Deadpool issues, of which you referenced a cover as a "properly" colored Domino, have an entirely different signature style than do Dell'Otto or Crain. For crying out loud, Zircher isn't a painter. He's a line-artist. These are different styles, and different renditions, and different finished products.
I've already explained Dell'Otto who, by the way, painting it himself is not making use of a colorist. I'm close to 100% sure Dell'Otto does it all himself.
Crain is also a painter, though he does it all digitally from my understanding, and I believe he also works solo and doesn't use a colorist. But his painted work is entirely different from other painters - Dell'Otto, for one, Stjepen Sejic, or a majority of the artists who work with Radical Publishing, or even, dare I say, Greg Land. Crain has always been muddy, and his colors are always very muted and similarly muddy. Surprise, surprise, muted and muddy white is going to look different and darker than a simple stark white as used by the UDON digital colorists. UDON is so blatantly simple in their coloring techniques, but it's always worked well with the type of line-art they deal with.
When you're dealing with certain styles, it's not miscoloring. It's the finished product of that type of work. If she was red, or black, or purple, I wouldn't be disagreeing. Variances of white, however, are still white. You don't ruin a piece of art by colorings one thing outside the rest of the art style.
