A comprehensive toolkit based on ComfyUI, providing image, mask, audio, and tools nodes, fully modular and v3 compatible.

ComfyUI-UniversalToolkit


Converts chosen RGB value to a mask based on color distance.

The node calculates the Euclidean distance between each pixel's color 
and the target RGB color. Pixels within the threshold distance are 
included in the mask (white), while others are excluded (black).

With batch inputs, the **per_batch** parameter controls the number 
of images processed at once for memory efficiency.

Parameters:
- RGB values: Target color to match (0-255)
- Threshold: Maximum color distance for inclusion (0-255)
- Invert: Flip the mask (exclude matching colors instead)
- Per batch: Number of images to process simultaneously
