The Color Grading effect alters or corrects the color and luminance of the final image that Unity produces. It is similar to applying filters in software like Instagram.

Low Definition Range: ideal for lower-end platforms.
High Definition Range: ideal for platforms that support HDRhigh dymanic range See in GlossaryrenderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info See in Glossary.
External: allows you to provide a custom 3D look-up texture authored in external software.

For more information on using Color Grading in Unity, see the Color Grading documentation in the Post ProcessingA process that improves product visuals by applying filters and effects before the image appears on screen. You can use post-processing effects to simulate physical camera and film properties, for example Bloom and Depth of Field. More info See in Glossary package.
