Please post pictures. Its hard to help someone when you cant see what they have already.

It’s hard to tell if your appliances lean to gray or not. I think a light bright green would be fun. I think the greens you have samples of are too dark. Like a leafy spring green. But as cat_ky says, it’s hard to know what to recommend unless we have some sense of your taste and color preferences.

The room appears to be a bit blah. I would go with something bright and cheerful in there. Nice to have a happy looking laundry room. I know, I spend a lot of time in mine, not just for laundry. I have a sewing machine in there, and a dog bed, and a long counter, that is used for several things. Bright, and cheerful, makes me happy to be in there. However, you havent given us any idea of what colors you like, etc.
