Gday Raz. I dont know of anyone fitting them to any other colour than white or yellow.

I can try a stuffup piece on a dark colour if you like to see how much change in colour there is.

The light colours like you say are hard to make them solid over dark paint. We have this issue with the DY4 kits. The white needs to be very solid. Working on it at the moment. Have done it with the HQ sandman white kits so dont see the issue with the DY4 kits.

Why not go with HX DX5 or HZ DY6 on a super mint? I think it would look tops.

Cheers
