# HSV Adjust Adjusts the hue, saturation and value of an RGB color by a vector . ## Parameter Types **HSV Adjust (color3f):** |Input |Type | |--------|-------------| |`In` |Color3| |`Amount`|Vector3f | |Output|Type | |------|-------------| |`Out` |Color3| **HSV Adjust (color4f):** |Input |Type | |--------|-------------| |`In` |Color4| |`Amount`|Vector3f | |Output|Type | |------|-------------| |`Out` |Color4| ## Parameter descriptions - `In`: The input color the node adjusts. - `Amount`: The adjustment of the HSV. The default value is `(0,1,1)`, which causes no change. ## Discussion The HSV Adjust node adjusts the hue, saturation, and value of the color passed to the `In` parameter. The node performs this adjustment by adding the first value of the `Amount` vector to the hue, multiplying the saturation by the second value of the `Amount` vector, and multiplying that value by the third value of the `Amount` vector. When adjusting the hue, a positive value rotates the hue in the direction of red to green to blue. A value of 1 represents an entire rotation, and results in no change. > Note: This node never changes the alpha of a `color4`. --- Copyright © 2026 Apple Inc.
