With dark wall paint such as navy, layering different light sources is critical to avoid gloomy spaces. Combine overhead ambient lighting with task lamps and accent lights to illuminate corners and highlight features. Use warm bulbs to add coziness and grazing lights to emphasize textured walls like brick or paneling. Dimmers provide flexibility for mood adjustments. This multi-layered approach balances navy’s light-absorbing quality, creating a calm yet well-lit room.
