# LUT

*Texture LUT* node applies a LUT, also known as Look Up Table, to an image. This node is useful for enhancing the color or contrast of an incoming texture.

## Setup

To use the node, you first have to insert it in the *Layer Layouts*. You can find it in the dedicated *Search bar*, under **Utilities -> Texture** collapsible.

Give the *Texture Lut* node a *Texture input* and connect it to an active *lifeline*.
