For Adobe Photoshop and After Effects programs, the saturation effect can be a tool to augment or reduce the density of the entire color spectrum used in a given image. This can be done using the channel control slider to adjust all colors at once automatically. The channel range is the composition of the colors that make up the overall channel control, where the two color bars stand in for the colors in their order in the color wheel. Use the upper bar to view the color saturation before making the adjustment; the bottom is used to show how the adjustment affects all the hues in the color saturation.
The master hue effect is part of color saturation in how it functions proportionally to the saturation effect. As with the saturation effect, the master hue also uses the color wheel to change hue. The numerical value displayed shows the number of degrees of rotation from around the wheel in relation to the original pixel value of the color. The values range from -180 to +180, with the positive value indicating a clockwise rotation around the color wheel; a negative value indicating a counter-clockwise rotation.
The colorize function of the saturation effect enables you to reduce the color spectrum of your image to all one hue. The colorize function is handy to add color to a gray-scale image, which is digitally converted to a Red-Green-Blue image, or otherwise can saturate additional color into an existing RGB image. When you select colorize, all the hues of the current foreground color are transposed onto the image without changing the original lightness of the pixelated colors. Dragging the slider enables you to quickly colorize saturation and lightness as a manual control of the saturation effect.
Choose the "Hue/Saturation" effect from the effects toolbar. In the Channel Control menu, first specify which colors you want to adjust; that is, would you rather adjust the colors of your image one at a time, or would you rather have the program automatically adjust them proportionally to one another? The master option will adjust all colors at once, whereas choosing a master color enables you to preset a color range for the color you wish to modify. Use the sliders for the Hue/Saturation effect to shift color away or toward the specified master color to create the saturation effect.
