LUT (Look up table) textures, are sprites used to map each possible color that the PC can represent into another. With look texture you can basically create color filters for the game.

A LUT texture looks like this:

To make your own one, you will need to take a neutral LUT texture (wich is a texture that map each color to itself, without adding any color correction) and edit it with an image editing software to add the desired color and light correction.

To make this easier, you can color correct a screenshot from the game with disabled color correction, and replicate the same applied correction to the neutral LUT texture. In this way the correction applied to the screenshot will be the same correction the LUT will apply to the game.

This screenshot is a non-color corrected image from the game, and the LUT texture inside it is the neutral lut texture.

So what you need to to, is to take this image, and with photoshop, gimp or similar softwares apply some color correction (hue shift, saturation, lightness change etc), then you will have to extract the LUT texture in an isolated image. Make sure the LUT stays 1024x32 pixels, as it is inside the screenshot.



In case you need the original Neutral LUT alone, this is the Neutral LUT extracted from the previous image. Neutral LUT basiclaly remap every color to itself, so it can be edited to make it remap the displayed colors to other colors to create your custom color correction.

Next step is navigating on your PC to the folder "C:\Users\YOURUSER\AppData\LocalLow\CorvoStudio\Easy Red 2\lut" (windows) or "~/.config/unity3d/CorvoStudio/Easy Red 2/lu/" (Linux) and place the created LUT texture inside it.


Now you can start the game, open settings menu, and the LUT texture you created will appear in the "color correction" dropdown:




Here is a video tutorial on how to realize a LUT Color Correction filter, and how to publish it into the Steam Workshop (Notice: To publish it into the workshop the Modding SDK is required)
