Changing the color of a channel

Color spaces have been developed as a means of describing color. Two of the most common color spaces are RGB (Red-Green-Blue) and CMY (Cyan-Magenta-Yellow). The former is used by monitors and the latter is usually used by printers. RGB and CMY can be difficult to understand.

Another color space, IHS (Intensity-Hue-Saturation) give a more accurate representation of how the eye interprets color. IHS transformations are useful in digital image processing, as they allow for greater control over the components that make up color.

You can change the color of any channel by clicking on its color chip. This opens the Line Color editor. The color representation of a channel's profile on the graph is changed.
