Shale is mostly made up of clay, so it can range in color from medium brown to white. Shale is often used to make ceramic tiles.
Shale colors fall in the neutral color palette and can be paired with blues for a country look, soft pinks for romantic style or gray tones for classic decor. When accented with gold accessories or gold-toned furniture, shale colors have a luxurious, elegant feel. Mixing shale tones with wood furniture or accents gives a room an earthy feel. Bright green or teal accents liven up a room that is decorated mainly with shale tones.
