You're going to regret it if you make the marquee overly pink. You need a little contrast to make the forms on your cabinet work, otherwise you'll get a bit of a monochrome blob. Make the pink in the marquee the accent color to pick up the cab, with something that will keep your theme like a baby blue or purple/lavender/magenta.
For instance, the new cab I'm building is is more of a medium to deep blue, but my marquee, side art, cp overlay and joystick balls and buttons are all pink and purple, with blue elements. You could go the opposite way.
I'm not a fan of the collage of classic art marquees myself, I think if you don't have nice custom artwork you'd be better off with something like some nice pink lettering over one of the aforementioned colors. Your call of course.
My 2 cents.
