HSVAdjust/HSLAdjust/HSIAdjust let's you rotate hues, control the strength of color (saturation), or modify the brightness of a clip. The type of brightness depends on the filter. It's value for HSVAdjust, lightness for HSLAdjust or intensity for HSIAdjust.
The adjust hue, saturation and brightness values are clipped to their valid ranges before they are converted back to RGB.
Note that all of the three spaces (HSV, HSL and HSI) are in fact approximations and the values are different with the exception that the hue in HSV and HSL coincide.
HSVAdjust (clip clip, float hue = 0, float
sat = 1, float bright = 0, float cont = 1)
HSLAdjust (clip clip, float hue = 0, float
sat = 1, float bright = 0, float cont = 1)
HSIAdjust (clip clip, float hue = 0, float
sat = 1, float bright = 0, float cont = 1)
