color-correction SKILL.md skillA
color-correction from artokun/comfyui-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add artokun/comfyui-mcp/color-correction@git:20260825.cab59a6Pins git:20260825.cab59a6 in mdr.lock. Pin the fingerprint instead.

Diagnose and fix video/image color OBJECTIVELY with the get_image (action:"analyze_color") tool (scopes/stats such as black/white points, contrast, saturation, clipping, cast) instead of eyeballing a contact sheet. Covers the "washed out" signature, why reference color-match (mkl/ColorMatch/ColorMatchAdobe) CAN'T add contrast a flat source lacks, the levels/contrast-stretch fix (core AdjustContrast / CurveEditor), the measure→fix→re-measure loop, the side-by-side sandbox pattern, and where to…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Color Correction (measure, don't eyeball)
## The core principle
You cannot reliably judge color from a storyboard or contact sheet. "Is it washed
out?" flip-flops by eye, especially on AI-gen video. Make color measurable with the
`get_image (action:"analyze_color")` MCP tool, read the numbers like a colorist reads scopes, pick the
fix the data points to, then re-measure to confirm. The whole skill is this loop:
```
extract a frame ─► get_image (action:"analyze_color") ─► read black/white points + contrast + saturation
▲ │
│ ▼
re-measure ◄──── apply fix (levels / contrast / match) ◄── diagnose from the numbers
```
> Origin: on a WAN-Animate render we argued for many turns over whether the clip was
> "washed out." The instant we measured it, the answer was unambiguous and the *correct*
> fix (a contrast stretch, not the color-match nodes we'd been adding) fell straight out.

How to install
mdr add artokun/comfyui-mcp/color-correction@sha256:68891fc396ad7794The line at the top of this page pins the label git:20260825.cab59a6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
