ComfyUI Node: ColorTransfer PM

ColorTransfer PM:

The PM_ColorTransfer node is designed to transfer the color distribution from one image to another, allowing you to harmonize the color palette between two images seamlessly. This node is particularly useful for AI artists who want to match the color tones of different images, ensuring a consistent and cohesive look across their artwork. By leveraging advanced color transfer algorithms, this node adjusts the color statistics of the source image to match those of the reference image, resulting in a visually appealing and professionally balanced output. Whether you are working on digital portraits, composite images, or any other creative project, PM_ColorTransfer helps you achieve a unified color scheme effortlessly.

ColorTransfer PM Input Parameters:

transfer_from

This parameter specifies the source image from which the color distribution will be transferred. The source image should be provided in a format that the node can process, typically as an image tensor. The color characteristics of this image will be adjusted to match those of the reference image specified in the transfer_to parameter.

transfer_to

This parameter specifies the reference image to which the color distribution will be matched. The reference image should also be provided in a compatible format, typically as an image tensor. The color statistics of this image will be used to adjust the colors of the source image specified in the transfer_from parameter.

ColorTransfer PM Output Parameters:

IMAGE

The output of the PM_ColorTransfer node is an image tensor that represents the source image with its color distribution adjusted to match that of the reference image. This output image will have the same dimensions as the source image but with a color palette that closely resembles the reference image, providing a harmonious and visually consistent result.

ColorTransfer PM Usage Tips:

• To achieve the best results, ensure that both the source and reference images are of similar dimensions and resolutions. This helps in maintaining the quality and consistency of the color transfer.
• Experiment with different reference images to see how various color palettes affect the mood and tone of your source image. This can be particularly useful for creating thematic series or collections of artwork.
• Use high-quality images with well-defined color characteristics for both the source and reference images to ensure a smooth and accurate color transfer.

ColorTransfer PM Common Errors and Solutions:

ValueError: Input images must have the same number of channels

• Explanation: This error occurs when the source and reference images have a different number of color channels (e.g., one is RGB and the other is grayscale).
• Solution: Ensure that both images are in the same color space and have the same number of channels before passing them to the node.

TypeError: Input images must be numpy arrays

• Explanation: This error occurs when the input images are not provided as numpy arrays.
• Solution: Convert your images to numpy arrays before passing them to the node. You can use libraries like OpenCV or PIL to handle the conversion.

RuntimeError: Image dimensions do not match

• Explanation: This error occurs when the dimensions of the source and reference images do not match.
• Solution: Resize the images to have the same dimensions before passing them to the node. This can be done using image processing libraries like OpenCV or PIL.
