color-correction

# 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. --- ## The `get_image (action:"analyze_color")` tool Read-only. Source = `asset_id`, a ComfyUI output ref (`filename`/`subfolder`/`type`), or an image `path` (absolute, or under the output dir). It returns per-image stats, heuristic flags, a one-line verdict, and optionally an overlaid R/G/B/luma histogram PNG. ``` get_image({ action: "analyze_color", filename: "render_00007_.png" }) # absolute numbers get_image({ action: "analyze_color", path: "frame.png", reference_path: "src.jpg" }) # + sho...
