1. Color mode
1. RGB: optical three primary colors, which is also the most widely used color mode
2. CMYK: Cyan, magenta, yellow, black for printing
3. Grayscale mode: the image does not contain colors, only three colors of black, white and gray, which will affect the subsequent use of colors
4. Decolorization (ctrl+shift+u): Minimize the saturation of the image, without affecting the color mode, and having no effect on the subsequent use of colors
5. Change mode: menu bar-image-mode
2. Toning
1. Adjustment panel: click on the effect to directly create a new layer, with its own layer mask, which can be adjusted multiple times and only works on the lower layer
2. Brightness/contrast: brightness
, increase/decrease the degree of image light and dark contrast, increase/decrease the degree of image light and dark contrast
3. Hue/saturation ctrl+u: hue, color appearance,
saturation, color vividness,
lightness, color lightness and darkness
, check coloring when making monochrome
4. Three primary colors: red, green and blue.
Complementary colors (reverse colors): colors that can cancel each other, 180° colors, opposite colors.
Three pairs of complementary colors: red and cyan, blue and yellow, green and magenta
5. Color balance (ctrl+b): can be adjusted according to the hue of the color
6. Gradient mapping: generally combine the blending mode and opacity to use. In layman's terms, use the color you set to correspond to the color of the original image. With this effect, some very exaggerated color matching effects can be achieved.
7. Optional color: adjust a single color,
"relative" is softer, "absolute" is more sharp, and relatively used more
8. Replace color: Image—Adjust—Replace Color Pick one color and choose another color to replace (you can use the add straw to add color)
