Defined in: packages/nodes/src/color/colorRemap.ts:62

Remap colors using a custom channel for lookup instead of luminance.

Parameters

inputColor

Node<"vec4">

The input color (vec4 with alpha)

Texture

Horizontal gradient texture for color lookup

lookupValue

FloatInput

Custom value for gradient lookup (0-1)

strength

FloatInput = 1

Effect strength (0 = original, 1 = fully remapped)

Returns

Node<"vec4">

Color remapped through gradient

Example

// Remap based on red channel
colorRemapCustom(texture(tex, uv()), gradientTex, inputColor.r)
