Color grading of complex color images

Quick answer：

Color grading refers to the process of adjusting and enhancing the color scheme in images or videos to achieve a desired aesthetic. In the case of complex color images, color grading can be more challenging due to the variety of colors and tones present. This process typically involves adjusting exposure, contrast, saturation, and color balance to create a consistent look and feel. Advanced techniques might also include using LUTs (Lookup Tables) for non-linear adjustments.
