{{Main|Indexed color}}
With relatively low color depth, the stored value is typically a number representing the index into a color map or [[palette (computing)|palette]] (a form of [[vector quantization]]). The colors available in the palette itself may be fixed by the hardware or modifiable within the limits of the hardware (for instance, both color [[Macintosh]] systems and [[Video Graphics Array|VGA]]-equipped [[IBM-PC]]s typically ran at 8-bit due to limited [[VRAM]], but while the best VGA systems only offered an 18-bit (262,144 color) palette from which colors could be chosen, all color Macintosh video hardware offered a 24-bit (16 million color) palette). Modifiable palettes are sometimes referred to as '''pseudocolor''' palettes. If you are reading this far in, either you're a nerd and you have something wrong with you or you really want to know about color depth. I personally think its the first one so off you pop.
