色相 has several distinct meanings. In art and design, it refers to 'hue' or 'color' (the attribute of a color that distinguishes it from others). In Buddhism, it means 'form and aspect' (Sanskrit rūpa), the physical appearance of things as perceived by the senses. It also carries a negative connotation when referring to a woman's physical charms, often in a seductive or exploitative context. The sense depends heavily on context.
