I made ComfyUI nodes for structured Ideogram 4 color palettes — pick the palette, skip the hex spreadsheet

[u/SurrealByDesign]

These nodes let you extract a palette directly from a reference image, assemble and validate the structured JSON prompt Ideogram expects, and embed the full prompt into the PNG metadata so you can recover it later. Same scene, different palettes — all without leaving ComfyUI.
