The laundry room, if you’re “lucky” enough to have one, is the one room in the home where you can have tons of fun with color.
Most laundry rooms have doors so if you would choose a color that is, a little out there, who cares! Just close the door.
The main thing is to choose color that you love and that feels fun to you. After all, you might as well be surrounded by your favorite colors while you’re in there right? Right.

I just looked at a house on line in my neighborhood with purple countertops in kitchen,master bath, and laundry room! It had been reduced 16,000. So much better to put your personal tastes in accessories and paint which can be changed .
You are so right!! I appreciate people adding color to their rooms but like you said, keep the color in accessories or walls, so you can change it out. Those countertops were a very expensive mistake.
