Hi,
Tray ceilings give you several options for painting. Do you have an idea of the look you'd like to achieve? You can paint the entire tray area in the wall color, then choose a darker color for the ceiling. Paint the tray and the ceiling in a lighter color, or even a combination of both. Do you have a look in mind for the room (is this a dining room?)
Please let me know, and I can make a few suggestions of colors to sample.

Thanks,
Diana
