Color decorating ideas are not always about painting walls in color. You can do it just with the multi color lighting fixtures and bunch of colored chairs. Pretty neat ha? This could be an interesting dining room idea, right there. And when you move you can take the colors with you but walls you cannot. Shown here is the PXL pendant in painted aluminum, a design by Fredrik Mattson. There is also a matching table lamp. Available from Svenssons.
