→CLUT (color lookup table)
<br/><center>[[Image:PSX_TIM_file_clut.png]]</center><br/>
The length of the CLUT data is always ''width'' × ''height'' × 2 bytes, precisely the amount of data needed to fill a rectangular area of ''width'' × ''height'' pixels in the frame buffer. Also, in the frame buffer CLUTs need x coordinate of the CLUT needs to be stored on an even multiples multiple of 16 horizontally, but the y coordinate can be stored freely on any rowvalue between 0-511. Typically they are stored directly under the front/back buffers. Each 16-bit value is interpreted as real color frame buffer pixels, which have the following format:

The red, green and blue samples behave like any RGB-defined color, but the STP (semi-transparency processing) bit has varying special meanings. Depending on the current transparency processing mode, it denotes if pixels of this color should be treated as transparent or not. If transparency processing is enabled, pixels of this color will be rendered transparent if the STP bit is set. A special case is black pixels (RGB 0,0,0), which '''by default''' are treated as transparent by the PlayStation ''unless'' the STP bit is set.
