Color Remap

Node icon
Color

Shifts a single color to a target color while preserving luminance, acting as a surgical hue replacement.

Color Remap finds pixels near a source color and shifts them toward a destination color. The hue tolerance controls how wide the affected range is, and the feather softens the transition at the edges of that range.

Unlike Palette Remap (which generates multiple variants), Color Remap produces a single output with one color changed. It preserves luminance by default, so shading and highlights stay intact.

Parameters

Section titled “Parameters”

Color

Source ColorColor (RGB)
Default: rgb(200, 50, 50)

Color to replace

Dest ColorColor (RGB)
Default: rgb(50, 100, 200)

Replacement color

Matching

Hue ToleranceNumber
Default: 30.0 Range: 1.0–90.0

Angular range around source hue to remap; wider=more affected

Min SaturationNumber
Default: 20.0 Range: 0.0–50.0

Below this saturation pixels are never remapped (grays stay)

FeatherNumber
Default: 0.2 Range: 0.0–1.0

Soft falloff at hue range edge; 0=hard, 1=gradual

Preserve LuminanceToggle
Default: true

Keep original brightness; shading and highlights preserved

Mask

Mask FitChoice
Default: None

Mask sizing

  • NoneCenter the mask at its native size — no resizing. Unmasked regions are unaffected.
  • StretchStretch the mask to exactly match the image dimensions. May distort the mask shape.
  • FitScale the mask to fit inside the image, preserving aspect ratio. Letterboxes where needed.
  • FillScale the mask to fill the image, preserving aspect ratio. Crops edges if aspect ratios differ.
Notes

Mask Fit only visible when mask is connected.

Pins: image (required), mask (optional). When mask is connected, the effect is blended with the original using the mask (white = full effect, black = original).

Usage Tips

Section titled “Usage Tips”
  • Use the eyedropper to pick the exact source color from the image.
  • Raise Min Saturation to avoid remapping gray/neutral pixels that happen to be near the source hue.
  • Increase feather for a smoother transition between remapped and unaffected areas.
  • Connect a mask input to limit the color replacement to specific regions of the image.
