# Transforming with lookup tables

Use lookup tables to apply color transformations to images.

## Overview

Overview Lookup table functions use the value of a source pixel as an index into a lookup table of colors that defines the corresponding destination pixel. You can use lookup table functions to perform tasks, such as color grading, converting between color spaces, or generating false-color images.
