I recently saw a picture of a room with pale green walls, white trim and creamy off-white painted furniture and accents and it looked really pretty. I think the key is to have enough contrast between the white and the bisque and to repeat the white in something else so it makes sense. If the white and the bisque are close and don't contrast much, that is what makes for a 'dirty' look on the off white color. If your trim is white that might do the trick. The other thing to keep in mind is that if everything else looks great together in the room, floors, walls, trim and cabinets the appliances will just sort of sit there being white and probably won't bother you. Especially since you say you have alot of cabinets, I think it would be fine. I can imagine that it would bother me if I had a small laundry with more washer/dryer area showing than cabinetry, then it would feel like the w/d were more prominent than the cabinetry. Hope that makes sense. :)

Placed the cabinet order today, and ended up doing two-tone. The cabinets above the washer and the sink cabinet are white, then the bench and lower shoe shelves are brown, while the frame around the bench and the cabinets above are white. The brown matches the brown kitchen island a few feet away. Crossing my fingers that this will turn out ok! I will post pictures in a few weeks when it is all installed.

first thing I would add is a long shelf to go above the appliances (when you get your new ones), see some of the pics below. Or, if doing front loading, then build a countertop to go over both. I added the long shelf on mine and love it. I also added a rail above to hang delicates and such. see how they've done here? top for folding and rail for hanging. for the 'back splash', you can jazz it up with a stencil, or paint or even some left over tile (you don't need much. check out craigslist for a few sq feet of marble tile or something cool) i just saw a kitchen that was done in white cabs, countertops, but they painted the ceiling in the most beautiful shade of turquoise. it looked so good. perfect idea for a sunny laundry room can't find a pic of it, but it resembled something like this one (just the ceiling. and you could do a satin, not glossy) you could do greens or yellows,,,whatever you like. I think the white cabs w/the blue ceiling is great you could also DIY some T&G on the ceiling or, pick a great color for the cabstand bring in a matching light if it's a small space, go bold w/the flooring. white subway tile is cheap and you can DIY here's that shelf I was referring to http://lovinghere.com/beautiful-small-laundry-room-reno-one-room-challenge-reveal-two-months-late/ something simple, or do a bit bigger:

Paint the laundry doors the same as the wall color. Let your eye move through to the back since you want the cabinets to be the showcase. The hutch color is a nice highlight and it will be the highlight if the laundry door remain in the background. The baseboards and trim are very thin. This might be the perfect scenario to paint the walls and trim the same color in different sheens.
