Camains, also known as "camaïeu," refer to a painting technique that employs a limited color palette, typically using variations of a single hue. This method emphasizes tonal contrast and can create a sense of depth and texture in the artwork. It is often used in art to explore shading and form without the distraction of multiple colors. The term may also refer to a specific style of decorative design in textiles or ceramics that utilizes similar color principles.
