The Selective Color effect adds or removes an absolute or relative percentage of the CMYK process color from the red, yellow, green, cyan, blue, and magenta color spectrums. You can also add color to the grayscale pixels in a color image.
The Selective Color effect has been used to adjust the color value in the green spectrum.
Selective color modifications increase and decrease the percentage of cyan, magenta, yellow, and black pixels that make up each primary color in the color spectrum. For example, decreasing the percentage of magenta in the reds spectrum results in a color shift toward yellow. Increasing the percentage of magenta in the reds spectrum causes a color shift toward magenta and an increase in red. The extent of any color modification depends on the adjustment percentage method you select.
