OC Palette Block

The easiest way to wreck an otherwise good character is a jacket in one color family, pants in another, and shoes that belong to neither. OC Palette Block is the ComfyUI-OC-Generator answer: one node that defines a coordinated color system, then lets every clothing slot dip into it. Instead of hand-typing "red top, red skirt, red shoes" and hoping the shades agree, you set a palette once and the pack distributes the colors for you.

It's marked as the pack's color brain for a reason. You connect its palette output to OC Character Outfit Block's palette socket, and each connected outfit part picks up a color according to its role. The defaults are sensible: upper and outer garments take a primary color, the lower half takes secondary, and small items - neckwear, jewelry, decorations, and notably the waist - default to the accent. Socks and shoes lean neutral. That split is why the palette carries up to three primaries: a two-tone outfit rotates through them per slot instead of painting everything the same shade.

What you actually set

Seven required inputs, of which four are the real deal:

• mode - fixed uses the colors you picked by hand; randomize throws your picks away and selects a preset from your chosen style.
• palette_style - balanced, monochrome, high_contrast, warm, or cool. In fixed mode it's mostly a semantic label; in randomize mode it's the family the preset is drawn from.
• primary_1 / primary_2 / primary_3 - up to three main colors. Extra primaries are what make an outfit read "coordinated" instead of "uniform."
• secondary, accent, neutral - the supporting cast. __none__ disables any of them.

Each color dropdown lists 142 named colors (aliceblue, forestgreen, the whole CSS gang, plus anime-familiar names like blonde). randomize is deterministic given the seed input, so you can reroll palettes reproducibly until one clicks.

Where the colors actually go

When a part resolves with a color role, the pack literally prepends the color name to the tag: red corset, navy school_uniform. That's it - no hex math, no conditioning. It works because anime SDXL models (Illustrious, NoobAI, Pony) understand color words in exactly that position, and it's a big part of why the whole pack can get away with being pure prompt text.

Three outputs: palette (structured OC_PALETTE data for the Character Outfit Block), palette_preview (a one-line summary like primary=navy+white, secondary=gray, accent=gold, neutral=black), and debug_text telling you which preset or manual path was used.

Gotchas

• randomize overrides everything you typed. Pick your colors carefully, then flip mode to randomize, and they're gone - the presets are baked into the pack.
• If a part looks wrong, check its color_role first. auto defers to the per-slot default; setting it to primary on every slot will make the whole outfit one color.

Install is the pack's usual light touch: ComfyUI Manager (search "ComfyUI-OC-Generator") or git clone https://github.com/Zhuozhuo-219/ComfyUI-OC-Generator into custom_nodes/, restart, done. No models, no pip dependencies.
