What this node does

Pseudocolor replaces the image’s colors by mapping luminance through a chosen palette (colormap). Dark-to-bright becomes a smooth gradient of the palette’s colors. Use it for thermal / heatmap styling, data-viz aesthetics, or bold stylized recolors. This is a rendered stage — it needs a ▶ Run and uses an ffmpeg pseudocolor filter. In goes COMFYTV_VIDEO, out comes COMFYTV_VIDEO. To hand the result to a native ComfyUI node, insert a Bridge. See bridges.md.

​
When to use it

  • Fake a thermal-camera / heatmap look.
  • Apply a scientific colormap (viridis, magma, turbo…) for a data-viz feel.
  • Bold stylized recolor of a shot.

​
Parameters

​
pseudo_preset

The palette to map onto. Default viridis. One of: magma, inferno, plasma, viridis, turbo, cividis, range1, range2, shadows, highlights, solar, nominal, preferred, total, spectral, cool, heat, fiery, blues, green, helix. These are ffmpeg’s built-in pseudocolor presets — magma/inferno/plasma/viridis/cividis/turbo are the familiar perceptual colormaps; heat/fiery/solar read as thermal; shadows/highlights emphasize those tonal ranges.

​
pseudo_opacity

0.0–1.0, default 1.0. How strongly the recolor is applied over the original. 1.0 is full false-color; lower it to blend the palette with the original image.

Tips

  • Lower pseudo_opacity for a tinted look that still keeps some of the original picture.
  • heat, fiery, and solar give the most “thermal camera” feel; viridis/turbo look most like scientific plots.
  • Chroma Shift — RGB-split / aberration, not a palette remap.
  • Posterize — reduce to a small number of flat colors.
