SMP · Color Generator (dict) (legacy)

FVM_SMP_ColorGenerator is the dict-emitting version of the pack's color palette generator, built for the legacy StructPromptMaker pipeline. Same underlying color-theory algorithm as FVM_ColorPaletteGenerator - same harmony types, same style presets, same seed-driven reproducibility - but instead of a palette_string and a swatch, it outputs a typed COLOR_PALETTE_DICT that SMP's combiners consume directly. If you're on an SMP workflow, this is how colors enter it.

The reason it exists as a separate node is the data shape. Where the modern color node hands you color names for a prompt string, this one produces a structured document with:

• Garment role colors - colors assigned to outfit roles (primary, secondary, accent, and so on) that the SMP OutfitCombiner substitutes into garment prompts.
• Atmosphere tokens - ambient_light and shadow_tone entries derived from the same palette, which the LocationCombiner uses to write scene lighting ("amber light, warm shadows") that matches the wardrobe colors. That's the genuinely nice touch: the palette drives both the clothes and the light, so a character doesn't end up in a crimson dress under blue moonlight.
• A raw_tokens substitution map - the internal token→color mapping both combiners apply when they resolve prompts.

Inputs and outputs

Inputs are the familiar color knobs: seed, num_colors (2–8), harmony_type (auto/analogous/complementary/split_complementary/triadic/tetradic/monochromatic), style_preset (the same 14), vibrancy, contrast, warmth. Outputs: color_palette (the typed dict - wire it into the SMP OutfitCombiner and LocationCombiner) and summary (a human-readable string of what the palette resolved to, for sanity checks without a ShowText).

Installing

cd ComfyUI/custom_nodes
git clone https://github.com/ping1979ping/comfyui-FVMtools

No extra dependencies. Restart ComfyUI; it's under FVM Tools/SMP/Generators.

The legacy framing

This whole SMP branch is superseded by the JB suite, and the author says so in the README. JB · OutfitBlock and JB · LocationBlock fold color generation into a single resolved-JSON node with none of the dict ceremony - for new work, use those. Where this node (and SMP generally) keeps value is the atmosphere token system: the modern blocks bake colors into the outfit but don't export an ambient_light/shadow_tone pair for the scene. If you want a palette that coordinates garment colors with scene lighting in one shot, that's a genuine SMP-only feature worth keeping in mind. Just know you're committing to the whole dict-pipeline stack to use it.
