Color Wheels - mix a color into shadows, midtones, or highlights of an image. Layer Masks - create adjustment layers and draw masks to apply color grading manipulations to a selected area of an image. RGB curves - control red, green, and blue channels independently. CMYK curves - control cyan, magenta, yellow, and key channels of CMYK color space. LAB curves - manipulate brightness (L), and A, B color channels of LAB color space - unlike RGB, LAB color channels don't affect brightness component, enabling more creative color manipulations. Hue vs Saturation curve - increase or decrease saturation of a color or a HUE range. Hue vs Hue curve - change colors by selective HUE shift. Hue vs Luma curve - adjust brightness of a color or a HUE range. Luma vs Saturation curve - adjust saturation of shades, midtones, and highlights. Luma vs Hue curve - shift HUE of shades, midtones, or highlights. Saturation vs Saturation curve - boost unsaturated and decrease over-saturated colors to create evenly saturated HDR like images.
