# Applying 3D LUTs and Colour Transforms to Viewports

You can apply 3D LUTs and colour transforms to individual viewports, and use different ones in different viewports. Any 1D LUT that is being used on the monitor becomes deactivated automatically.

The nicknames of the available colour transforms also appear on the Viewer Colour Management pop-up menu, and can be used quickly apply a colour transform to the viewport.
