A dark green kitchen can feel unwelcoming if color contrast is low, lighting is cool or insufficient, and paint sheen is matte. These factors create a moody, heavy atmosphere. To fix this, brighten the space by introducing warm layered lighting, adjust paint to satin or semi-gloss sheen to reflect light, and lighten heavy cabinetry or add metallic accents. A cohesive color strategy and balanced lighting instantly enhance warmth and airiness.
