Color Grading (Color grading / Color correction) is a technical term that is extremely important in the rendering and optimization of game graphics (technical art). An explanation of color correction technology that modulates the hue, contrast, saturation, and brightness balance of the final rendered screen with high precision to infuse a specific atmosphere (retro, horror, cinematic, etc.) into the entire game.
Real-world analogy: A developing magic that instantly dyes an ordinary photograph taken into a superb antique or sci-fi cinema-like atmosphere by passing it through a photo editing app's ``Professional Development Filter (Color Adjustment)''
By applying detailed color make-up (grading) to the raw 3D graphics (a neutral state with no sex appeal), as if supervised by a real movie director (color director), such as ``shading areas are a little cold and blue, and areas that are hit by light are shifting to a warm orange,'' the world's persuasiveness and artistic quality are instantly raised to the highest level.
