# Palette
In [computer graphics](graphics.md) palette is a set of possible [colors](color.md) that can be displayed, the term usually refers to a selected smaller subset of all colors that can in theory be displayed (large sets of colors tend to be called [color spaces](color_space.md) rather than palettes). Nowadays mainstream computers are powerful enough to work with over 6 million 24bit [RBG](rbg.md) colors (so called True Color) practically without limitations so the use of palettes is no longer such a huge thing, but with resource-limited machines, such as [embedded](embedded.md) devices and older computers, the use of palettes is sometimes necessary or at least offers many advantages (e.g. saving a lot of memory). Nevertheless palettes find uses even in "[modern](modern.md)" graphics, e.g. in the design of image formats that save space. Palettes are also greatly important in [pixel art](pixel_art.md) as an artistic choice.

Palettes are also greatly important in [pixel art](pixel_art.md) as an artistic choice.
Palettes usually contain a few to few thousand colors and the number is normally a power of 2, i.e. we see palettes with number of colors being 8, 16, 256, 2048, etc. -- this has advantages such as efficiency (fully utilizing color indices, keeping memory aligned etc.). Palettes can be general purpose or specialized (for example some image formats such as [GIF](gif.md) create a special palette for every individual image so as to best preserve its colors). Palettes can also be explicitly stored (the palette colors are stored somewhere in the memory) or implicit (the color can somehow be derived from its index, e.g. the [565](rgb565.md) palette).
