CHANGE_CLOTHING_COLOR_FEATURE

Purpose: Add a boolean option to the Gemini Util - Options node to instruct Gemini to change clothing colors in descriptions to new, scene-harmonized hues that differ from the original colors.

What changed

  • New option in Gemini Util - Options:
    • Name: change_clothing_color
    • Type: Boolean (Yes/No)
    • Default: No
    • Location: nodes/nodes.py under GeminiUtilOptions.INPUT_TYPES
  • Propagated through the options object as change_clothing_color: bool.
  • Used by both image and video prompts to adjust clothing color language when clothing descriptions are enabled.
  • Included in caching options to avoid stale results when toggled.

Behavior

  • When describe_clothing is Yes AND change_clothing_color is Yes:

    • Text2Image prompt: In the CLOTHING paragraph, the model is instructed to state NEW clothing colors that harmonize with the scene (complementary/analogous/neutral), explicitly different from the original. The prompt forbids mentioning or comparing to the original color.
    • ImageEdit prompt: Adds a clause to change all clothing colors to NEW, scene-harmonized hues, explicitly different from the original; do not mention or reuse the original colors.
    • Video prompt: Same as image—CLOTHING paragraph instructs changing to NEW scene-harmonized hues and never referencing the original.

  • When describe_clothing is No: The color-change logic is ignored.

Files touched

  • nodes/nodes.py
    • Added change_clothing_color to GeminiUtilOptions.INPUT_TYPES
    • Updated GeminiUtilOptions.create_options signature and returned options
    • Propagated option into MediaDescribe.describe_media
    • Updated _process_image and _process_video prompts and cache keys
  • No changes needed in web/js/swiss-army-knife.js because ComfyUI auto-renders standard widgets for Python-defined inputs for the Options node.

Validation

  • Import check: from nodes.nodes import NODE_CLASS_MAPPINGS loads successfully
  • Expected available nodes include GeminiUtilVideoDescribe or GeminiUtilMediaDescribe depending on current implementation; in this repo: GeminiUtilMediaDescribe, GeminiUtilOptions, FilenameGenerator.

Usage

  1. Add Gemini Util - Options node to your workflow.
  2. Enable Describe clothing and toggle Change clothing color to Yes.
  3. Connect the options to Gemini Util - Media Describe and run.
  4. For image workflows, the final_string will include updated clothing colors; for video, the description will reflect new scene-harmonized clothing colors.

Notes and future considerations

  • Color selection is model-driven guidance; ensure the downstream model uses the prompt accordingly.
  • If you want to force a particular palette family (e.g., warm neutrals), a future enhancement could expose a clothing_color_palette_hint string.
