Invert

Node icon
Color

Inverts image channels, flipping colors to their complement per channel or all at once.

Invert subtracts each pixel value from 255, producing the complementary color. Red becomes cyan, white becomes black, etc. Each channel (R, G, B, A) can be inverted independently.

Alpha inversion is off by default to preserve transparency. Enable it when you need to flip a mask or alpha channel.

Parameters

Section titled “Parameters”

Color

Invert RedToggle
Default: true

Invert red channel (255 - value)

Invert GreenToggle
Default: true

Invert green channel (255 - value)

Invert BlueToggle
Default: true

Invert blue channel (255 - value)

Invert AlphaToggle
Default: false

Invert alpha channel; off by default to preserve transparency

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”
  • Invert only the Alpha channel to flip a mask, so selected becomes unselected.
  • Combine with Composite (Difference mode) for creative effects.
  • Connect a mask input to invert only specific regions of the image.
