Mix color channels in Pixelmator Pro on Mac
You can create dramatic color effects and custom corrections by modifying how individual color channels contribute to your final image. The Channel Mixer lets you remix the fundamental building blocks of color with controls that affect the red, green, and blue channels of an image. You can strengthen or weaken how much each input channel contributes to each output channel, creating unique color relationships and effects.
Understanding complementary color theory is helpful: Red affects cyan, green affects magenta, and blue affects yellow. Adding more of a specific color to a channel subtracts that color’s complementary color from the channel.
In Pixelmator Pro on Mac, select a layer in the Layers sidebar.
Select
in the Tools sidebar, then turn on Channel Mixer in the Color Adjustments pane.
Select a color channel tab (Red, Green, or Blue).
Adjust any of the following sliders:
Red: Drag to increase or decrease the red contribution to the selected channel.
Green: Drag to increase or decrease the green contribution to the selected channel.
Blue: Drag to increase or decrease the blue contribution to the selected channel.
Constant: Drag to adjust the brightness of the selected channel. For example, increasing Constant in the blue channel brightens the channel, making the image appear more blue. Decreasing Constant in the blue channel darkens the channel, making the image appear more yellow (blue’s complementary color).
Tip: Keep the total values of the four values in any channel at 100% to maintain brightness in the image as you modify its channels.
