There's some interesting color combos going on in this pic. The muted green walls and the dark and glossy green door and the more lime green chair. Kind of fun to see so many variants of a single color.
I chose this picture to represent the triadic colour scheme because it contains yellow, red and blue. The square pillow is yellow-green, the striped pillow is red-orange, the side table is blue-green and the flowers are orange-yellow.
