ComfyUI Node: Flatten Colors-Vextra

Flatten Colors-Vextra:

The Flatten Colors node is designed to simplify the color palette of an image by reducing the number of distinct colors it contains. This process, known as color quantization, is particularly useful for creating a more uniform and stylized look in your images, which can be beneficial for various artistic and design purposes. By limiting the number of colors, you can achieve a more cohesive visual effect, making the image appear cleaner and more polished. This node is especially useful for creating images with a specific aesthetic or for reducing the complexity of images for further processing.

Flatten Colors-Vextra Input Parameters:

images

This parameter accepts a list of images that you want to process. Each image should be in the format of a tensor, which is a multi-dimensional array used to store the pixel data. The images are the primary input for the node, and they will undergo the color flattening process to reduce the number of distinct colors.

number_of_colors

This optional parameter allows you to specify the number of colors you want the output image to contain. The default value is 5, but you can set it to any integer between 1 and 4000. Lower values will result in a more pronounced flattening effect, with fewer colors and a more stylized appearance, while higher values will retain more of the original color detail. Adjusting this parameter helps you control the extent of color reduction to achieve the desired visual effect.

Flatten Colors-Vextra Output Parameters:

IMAGE

The output of this node is a tensor representing the processed image(s) with the flattened color palette. The resulting image will have a reduced number of distinct colors, as specified by the number_of_colors parameter. This output can be used for further processing or directly in your artistic projects to achieve a more uniform and stylized look.

Flatten Colors-Vextra Usage Tips:

• Experiment with different values for the number_of_colors parameter to find the optimal balance between color reduction and image detail for your specific project.
• Use this node to create a cohesive visual style across multiple images by applying the same color flattening settings.
• Combine this node with other image processing nodes to enhance the overall artistic effect, such as applying filters or adjusting brightness and contrast.

Flatten Colors-Vextra Common Errors and Solutions:

"Input image tensor is None"

• Explanation: This error occurs when the input image tensor is not provided or is invalid.
• Solution: Ensure that you provide a valid image tensor as input to the node. Check that the image data is correctly loaded and formatted.

"Invalid number of colors"

• Explanation: This error occurs when the number_of_colors parameter is set to a value outside the allowed range (1 to 4000).
• Solution: Adjust the number_of_colors parameter to be within the valid range. The default value is 5, and you can set it to any integer between 1 and 4000.

"Image conversion failed"

• Explanation: This error occurs when the node fails to convert the input image tensor to a PIL image for processing.
• Solution: Ensure that the input image tensor is correctly formatted and contains valid image data. Check for any issues in the image loading or preprocessing steps.
