Color Grading, a term borrowed from the film industry, refers to the use of color to create or enhance a Scene’s mood. Here, we’ll explore Unity’s Color Grading tools.

Select the Post-Process Volume in the Hierarchy view.

In the Post-Process Volume Inspector, click Add Effect.

If you’d like to use high-definition Color Grading, be sure to set Color Space in your project’s Player Settings (Other Settings > Rendering) to Linear.

1. Check the box next to Saturation in the Tone section. Drag it all the way to 100 for a modern fantasy or comic book feel (Figure 01), or down to -100 to completely remove all color (Figure 02). 

2. Saturation also works in combination with other effects. Set it to -100 and add a color filter (Figures 03-04).

Figure 01: A Saturation level of 100 can take your visuals over the rainbow or down the rabbit hole.

Figure 02: Setting Saturation to -100 is great for creating classic noir or monster movie moods.

Figure 03: Color filters can add dramatic flair to black-and-white images.

Figure 04: Color filters can enhance even black-and-white Scenes.

Use Color Filter to create a subtle filmic look (Figures 05-06) or a dramatic alien-like or apocalyptic sky (Figures 07-08). 

Figure 05: A pale red or brown can give the feel of dusty, vintage analog film footage.

Figure 07: Unexpected colors work to add a sense of alarm or unease

Perhaps the most versatile, powerful effect in the Color Grading toolbox are the Trackballs, which function as color correction wheels to tint the shadows, midtones, and highlights of your image (Figures 09-10). This is useful for setting a certain mood or color motif, or recreating classic warm/cool color combinations.

Figure 09: If you’ve worked with color correction wheels, the Trackballs will feel familiar.

This has been a quick tour of just a few of the options available in the Color Grading toolbox. Try mixing and matching to find a combination that’s right for your project.
