Color decorating ideas do not always involve painting the walls in color. You can do it simply with the multicolored light fixtures and the group of colored chairs.
Pretty nice? This could be an interesting idea of dining, right there. And when you move, you can take the colors but the walls can not.
Here we see the PXL pendant in painted aluminum, designed by Fredrik Mattson. There is also a matching table lamp. Available at Svenssons.
