Palette (computing)
open-in-new
<p>In <a href="/facts/Computer_graphics/lapBE8wv">computer graphics</a>, a palette is the set of available colors from which an image can be made. In some systems, the palette is fixed by the hardware design, and in others it is dynamic, typically implemented via a color lookup table (CLUT), a correspondence table in which selected colors from a certain <a href="/facts/Color_space/zFvEyfHv">color space</a>'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 needed to describe the actual colors in the color space, this technique aims to reduce data usage, including processing, transfer bandwidth, RAM usage, and storage. Images in which colors are indicated by references to a CLUT are called <a href="/facts/Indexed_color/ljGwHMGE">indexed color</a> images. </p>
