I had a mosiac votive candle holder I bought in Spain. I wanted to capture the tonal shift of the colors on the walls in my room. I also always felt that the dark wood of my bed didn't show the beautiful carving in the wood so I changed it to gold.
Colors used in my room:
Deep and light pinks, gold, a multitude of greens, teal.
Tips for using color successfully:
Don't be shy. If you love it, go for it. It is important, however, that when you choose a color to be sure the tonal aspect of that color complements your skin tone.
