hueShift(inputColor, angle): Node<"vec4">

Defined in: packages/nodes/src/color/hueShift.ts:21

Shift the hue of a color using a rotation matrix in RGB space. This is more efficient than RGB->HSV->RGB conversion.

Parameters

inputColor

Node<"vec4">

The input color (vec4 with alpha)

angle

FloatInput

Hue shift angle in radians (0 to 2*PI for full cycle)

Returns

Node<"vec4">

Color with shifted hue

Examples

// Shift hue by 90 degrees
hueShift(texture(tex, uv()), Math.PI / 2)

// Animate rainbow effect
hueShift(texture(tex, uv()), timeUniform)
