Green can turn muddy when every surface has the same depth. Mix a pale sage, a deep leaf tone, and one yellow-green accent for movement.
Tune the atmosphere
Keep the largest area in the quietest green and save the strongest shade for a plant pot, cushion, or artwork. Natural daylight will do much of the blending.
Notice the change
Variation makes a green room feel like a garden in changing light rather than a single-color box.
