# Understand lookup textures
|
||
|
|
|

|
|
Lookup textures (LUTs) are color cubes that HDRP can apply to produce a final color-graded image. HDRP takes the original image color as a vector and then uses that to address the LUT to get the graded value. LUTs for the High Definition Render Pipeline (HDRP) use a CUBE file.
|

The guides in this section describe how to create an sRGB-targeting CUBE file with different external software, import it into a Unity Project that uses HDRP, and use it for [color grading](https://en.wikipedia.org/wiki/Color_grading) in your Scene.
