ComfyUI Extension: ComfyUI-Color_Transfer

ComfyUI-Color_Transfer Introduction

ComfyUI-Color_Transfer is an innovative extension designed to enhance your digital artwork by transforming the color palette of your images. This tool allows you to replace the dominant colors in an image with a new, custom color palette of your choice. Whether you're looking to harmonize your artwork with a specific theme or simply want to experiment with different color schemes, ComfyUI-Color_Transfer provides a straightforward solution. By using this extension, AI artists can easily achieve a cohesive look across multiple pieces or explore new creative directions without the need for extensive manual editing.

How ComfyUI-Color_Transfer Works

At its core, ComfyUI-Color_Transfer operates by analyzing the colors present in your image and then substituting them with colors from a target palette that you define. Imagine your image as a canvas filled with various shades and tones. This extension acts like a digital paintbrush, carefully selecting and replacing these colors to match your desired palette. The process involves two main steps: color clustering and palette transfer.

Color clustering groups similar colors in your image, making it easier to manage and replace them. The extension uses a method called MiniBatchKMeans, which is efficient and quick, though it may sometimes trade off a bit of accuracy for speed. Once the colors are clustered, the palette transfer step replaces these clusters with the colors from your chosen palette, giving your image a fresh and unified look.

ComfyUI-Color_Transfer Features

• Color Palette Node: This feature allows you to define your desired color palette using RGB values. You can specify colors in a simple format like [(Value, Value, Value), ...]. For example, a palette might look like [(30, 32, 30), (60, 61, 55), (105, 117, 101), (236, 223, 204)]. This flexibility lets you tailor the palette to suit your artistic vision.
• Palette Transfer Node: Once your color palette is set, the Palette Transfer Node takes your image and applies the new palette. This node is the heart of the extension, seamlessly integrating your chosen colors into the image.
• Customizable Clustering and Distance Methods: You can adjust the color clustering and distance comparison methods to fine-tune the results. The default setting uses MiniBatchKMeans for faster processing, but you can explore other methods if you need more precision.

ComfyUI-Color_Transfer Models

Currently, ComfyUI-Color_Transfer does not include multiple models. The extension focuses on providing a streamlined and efficient process for color palette transfer using the features and methods described above.

What's New with ComfyUI-Color_Transfer

As of the latest update, ComfyUI-Color_Transfer has introduced improvements in the speed and efficiency of the color clustering process. The use of MiniBatchKMeans as the default method ensures that even large images can be processed quickly, allowing you to spend more time creating and less time waiting.

Troubleshooting ComfyUI-Color_Transfer

If you encounter any issues while using ComfyUI-Color_Transfer, here are some common solutions:

• Import Error: If you experience an import error, ensure that the necessary Python package is installed. You can do this by running the command pip install scikit-learn in your command line interface.
• Color Palette Issues: Make sure your color palette is correctly formatted. Each color should be an RGB tuple, and the entire palette should be enclosed in square brackets.
• Unexpected Results: If the color transfer doesn't look as expected, try adjusting the clustering method or the number of clusters to better match the complexity of your image.
