Answer:
palette, also called color lookup table (CLUT), is a correspondence table in which selected colors from a certain color space's color reproduction range are assigned an index, by which they can be referenced. By referencing the colors via an index, which takes less information than the one needed to describe the actual colors in said color space, this technique aims to reduce data usage, be it as processing payload, transfer bandwidth, RAM usage or persistent storage. Images in which colors are indicated by references to a CLUT are called indexed color images.
