Basement laundry room with bright blue color
Blue is a soft yet calming color, especially the kind of blue showed in the picture above. You seem like never go wrong with this color especially if you pair it with the shades of gray or white.
The cabinets and other fixtures are recommended to be white or shades of gray as well. Since the basement tends to be a darker spot than other rooms in the main house, the bright color could help with it.
