Green walls come in a variety of shades, from pale greens, to bright greens, to dark green, and all will be accentuated with different colors. If you have pale green walls, then they will go well with other colors in what is known as the ice cream palette, for example pale pink and pale yellow. Alternatively, grass green will look much nicer teamed with regal colors, such as rich shades of purple and gold. Finally, dark shades of green go well with lime green, silver and other lighter colors. If you were to place dark furniture in a room with dark green walls then it would look very gloomy indeed.
