Every year Pantone comes out with the colour of the year. Emerald is out and Radiant Orchid is in!! I am not the biggest fan of purple but this colour is starting to grow on me. For interiors I think this colour would be perfect as an accent colour with whites and greys. If you are feeling bold though you could paint a room this colour.
Here are some great interior spaces that I think have successfully used Radiant Orchid.
