The Hue/Saturation tool is a combination of Primary Saturation and Secondary Hue controls.

Hue is a powerful tool because it can dramatically shift the color value of your image. Saturation increases or decreases the saturation or vibrancy of the colors in the image with precise control in linear light.

Hue: Offsets the color of the selected color. The number value takes you that number of degrees around the color wheel, from 0 to 360 degrees. Positive/higher values move the color sample counter-clockwise along the color wheel. Lower/negative numbers sample clockwise along the color wheel.

Saturation: The total amount of saturation in the image, on all channels. This raises or lowers the colorfulness or intensity of color of your footage.

Component Balance: Weights the operation to favor a particular color.
