Painting my retail store. - Color give support to please!? I'm looking to make the prevalent wall a light ginger, i'm not...

I'm looking to make the prevalent wall a light ginger, i'm not sure if i can paint the ceiling - due to the material. so i want an idea to contrast the feathery orange walls/ and the ashen white roof. I want to put a mid wall trim, and base board trim.

If you hold better ideas for a fundamental color, lay out your idea, otherwise what should my trim be.

Thanks
I stipulation to find?

Its ok to keep hold of you ceiling white. Now depending on what you retailing colors do effect the mood. So if your selling like bed and tub, blue and greens are your cool colors, make you quiet and relaxed. Your light red is a great color for just around anything else, cloths, sports nic nacs, etc. Its a warm and joyful color and more enegeric. I think frothy orange is a suitable choice!
