ComfyUI Node: Color Blend

Color Blend:

The Color Blend node is designed to merge two images using various blending modes inspired by Photoshop's color blending techniques. This node allows you to combine the color properties of one image with the luminosity or other attributes of another, creating visually appealing and artistically enhanced results. By leveraging different blending modes such as Hue, Saturation, Color, and Luminosity, you can achieve a wide range of effects, from subtle color adjustments to dramatic transformations. This node is particularly useful for tasks like face swapping, artistic photo editing, and any scenario where nuanced color manipulation is required.

Color Blend Input Parameters:

blend_image

The blend_image parameter represents the image that will be blended onto the base image. This image provides the color information that will be used according to the selected blending mode. The quality and resolution of this image can significantly impact the final output, so it is advisable to use high-quality images for best results.

base_image

The base_image parameter is the image onto which the blend image will be applied. This image serves as the foundation, retaining its original structure while adopting the color properties from the blend image based on the chosen mode. Like the blend image, the quality and resolution of the base image are crucial for achieving optimal results.

mode

The mode parameter determines the blending mode to be used. The available options are "Hue", "Saturation", "Color", and "Luminosity". Each mode affects the images differently:

• Hue: Uses the hue from the blend image and the saturation and luminosity from the base image.
• Saturation: Uses the saturation from the blend image and the hue and luminosity from the base image.
• Color: Combines the hue and saturation from the blend image with the luminosity from the base image.
• Luminosity: Uses the luminosity from the blend image and the hue and saturation from the base image. Choosing the appropriate mode depends on the desired effect and the specific characteristics of the images being blended.

Color Blend Output Parameters:

IMAGE

The output parameter IMAGE is the resulting image after applying the selected blending mode. This image combines the properties of both the base and blend images according to the chosen mode, producing a new image that reflects the intended artistic or corrective adjustments. The output image retains the dimensions and general structure of the base image while incorporating the color attributes from the blend image.

Color Blend Usage Tips:

• Experiment with different blending modes to see how each affects the final image. Each mode can produce vastly different results depending on the images used.
• Ensure both the base and blend images are of high quality and similar resolutions to avoid unwanted artifacts or distortions.
• Use the Color Blend node for tasks like face swapping or artistic edits where subtle color adjustments can significantly enhance the visual appeal.

Color Blend Common Errors and Solutions:

Unsupported blend mode: <mode>

• Explanation: This error occurs when an invalid blending mode is specified.
• Solution: Ensure that the mode parameter is set to one of the following valid options: "Hue", "Saturation", "Color", or "Luminosity".

Images must have the same dimensions

• Explanation: This error occurs when the base and blend images have different dimensions.
• Solution: Make sure both images are of the same size before blending. You can resize one of the images to match the dimensions of the other using image editing software or preprocessing steps.
