Video Color

Most "color" nodes in ComfyUI are a brightness and contrast slider with a coat of paint. Video Color is not that. It's the node you reach for when an AI render comes out looking like it was graded by a vending machine - too warm, milky shadows, no separation between tones - and you want to fix it the way an actual colorist would.

It's a ComfyTV VideoFX stage with the pack's canvas model: own Run button, snapshot output, and FX-chain participation so you can preview live and render once.

The inputs, grouped the way you'll actually use them

• Exposure and level: exposure (−3 to 3, default 0), black (−0.1 to 0.1), blackpoint (−0.5 to 0.5), whitepoint (0.5 to 2, default 1). Exposure moves the whole midtone range like an f-stop; blackpoint/whitepoint set where the blacks clip and the whites sit.
• White balance: temperature (1000–40000 K, default 6500) with temp_mix (0–1) to blend how hard it applies. The classic "too orange, cool it down" fix.
• Saturation family: hue (−180 to 180), saturation (−1 to 1), vibrance (−2 to 2). Vibrance is the one that protects skin tones while boosting everything else - reach for it before plain saturation, which will happily push faces toward the sun.
• The wheel: shadows_r/g/b, midtones_r/g/b, highlights_r/g/b (−1 to 1 each). This is the lift-gamma-gain structure: tint the shadows one way, the highlights another, independently.
• preserve_lightness (default on) - when you tint with the wheel, keep the luminance steady so you're shifting color without shifting brightness.

The project_id / parent_output_id / force_run_token inputs are internal frontend plumbing - ignore them.

How it works

This is a real color-grade node in the "color wheels" tradition: nine zone-per-channel controls arranged as shadow/midtone/highlight wheels, plus exposure, temperature, and point controls on top. The pack's own docs call the wheel setup lift-gamma-gain, which is the pro vocabulary for "dark, middle, and bright tones get independent color." That separation is the whole point - a warm highlight and a cool shadow can coexist, which is exactly the look flat sliders can't produce.

Install

ComfyTV ships ~190 stages in one pack; installing the pack gives you this node.

cd ComfyUI/custom_nodes
git clone https://github.com/jtydhr88/ComfyTV

Restart ComfyUI fully and find it under ComfyTV → VideoFX. ComfyUI Manager also finds it by searching "ComfyTV". No model downloads, no extra Python deps - it's deterministic color math on the clip. On ComfyUI Desktop or macOS, clone into the running instance's absolute path from the startup log rather than trusting the relative cd.

Troubleshooting

• Colors shift but the image gets darker. Toggling preserve_lightness off lets wheel tints drag luminance with them; keep it on unless you want that.
• "Saturation" makes faces glow. Switch to vibrance - that's literally the knob designed to not do that.
• The grade looks flat. You're probably using exposure alone. Add a blackpoint/whitepoint pass to set contrast first, then wheel the shadows and highlights separately.

It's more knobs than a beginner wants, but that's the point: this is the one color node in the pack you'd actually use to finish a clip.
