My trim is BM stock super white as is my flat ceiling. Sorry that I can't help with a tray ceiling.

i have a 'modified tray' of sorts in our sitting room and i painted the walls and the entire ceiling with the revere pewter...it's such a light color...
i used ballet white for the trim which seemed to go well with all the colors in the 3 adjoining rooms(bath, SR and MBR).

i have revere pewter in my pantry, with fnb slipper satin trim

if you want lighter, I'd try bm cotton balls

how high is your ceiling? maybe cut revere pewter 50pct white for the interiors of the trays

My ceilings are 9' high. The tray is basically 3 layers. I do have a lot of BM Simply white left over from my bathroom painting that was recently done. Is that too stark white or should I go with something like Dove White?

If I stick with revere pewter I'll probably use cotton balls for the trim. The sales clerk at the store suggested it and I think she was right. It's nice and bright but not too stark. I think there wouldn't be much contrast with the dove white, it might look dirty.

I have Revere Pewter in my master bed and bath and my trim is White Dove. Looks great.

I'd do the ceiling at 50% as suggested above.

Our trim and doors are painted with Dunn Edwards Swiss Coffee.

I'm very excited to getting around to painting my bedroom this weekend. Need to decide on trim paint colors. I have decided on BM Revere Pewter for the wall color and a 50/50 cut on the tray. My questions are:
1. Do I do the bottom of the tray, inside edge and ceiling all with the 50/50 cut?
2. What trim color if I don't want it to look to dirty? I have a lot of Simply White leftover from my bathroom but I think that may be too crisp of a white with RP.

I appreciate all your suggestions!
