Color management allows you to get the advantages of a scene-linear workflow, while still seeing a preview that is appropriate for your display in the viewport and Texture Baking View.
Enable color management in the scene. In addition to activating Enable Color Management in the Color Management preferences, there are certain other settings that you should check. See Configure color management manually.
When you add 2D File textures and other image inputs to your scene, you need to specify their input Color Space if it is different from the default that you specified when setting up color management. See Add color-managed textures and other image inputs for more information.
As you work, the view transform provides a preview of the final colors in the viewport and Texture Baking View. However, you can temporarily toggle the view transform off or choose a different one for diagnostic or other purposes. See Preview color-managed scenes.
The defaultViewColorManager node is still available in scenes for compatibility. However, its options are not used.
