Yes, bright white. Off whites will look dingy. If you can't find one that's as white as your trim, try a very pale oyster gray, a shade between your walls and the trim, if you can find such a thing in ready-mades.

I would just change the sheen unless you want more contrast. I would not use White Opulence in this situation because they are both too close but too different. It would be just "off" in that head scratching way. Now I do know White Opulence very well,as I've used it for all my trim and all the kitchen cabs in this house.

i say go with a white or a really light gray can pare nicely

@kel_kat5 How wide is the counter space in each of those three options with the various pantry sizes? How big is your family? I'm considering a 15" pantry which seems quite small in comparison to most I've seen, but I live alone and currently have no pantry at all, so I think any tall cabinet would seem luxe!
