so much of the time, people worry over colors "going together". but sometimes the colors that contrast are a better fit than going monochromatic. adding shades of a hue adds interest and depth. like these mint walls, sage armchairs, and emerald lamp shade. in this little room, the three variations of green paired with white and pink, look eclectic and whimsy. if the walls, chairs, and shade matched, the room would look a little boring and washed out.
