ComfyUI Node: 🎨 Sample Image as Palette

Sample Image as Palette [Dream]:

The "Sample Image as Palette" node is designed to extract a color palette from an input image, which can be used for various artistic and design purposes. This node allows you to sample a specified number of colors from the image, providing a way to capture the essence and mood of the image through its colors. By using a random seed, the node ensures that the color sampling can be consistent or varied, depending on your needs. This functionality is particularly useful for AI artists who want to create artworks that harmonize with the color scheme of a given image or for those who need to generate color palettes for design projects.

Sample Image as Palette [Dream] Input Parameters:

image

This parameter accepts an image from which the color palette will be sampled. The image serves as the source of colors, and the quality and variety of the palette depend on the image's content.

samples

This parameter specifies the number of color samples to be extracted from the image. The default value is 1024, with a minimum of 1 and a maximum of 4096. Increasing the number of samples can provide a more detailed and diverse palette, while fewer samples may result in a more simplified color scheme.

seed

This parameter sets the seed for the random number generator used in the sampling process. The default value is 0, with a minimum of 0 and a maximum of 0xffffffffffffffff. Using the same seed will produce the same palette for the same image, allowing for reproducibility. Changing the seed will result in a different set of sampled colors.

Sample Image as Palette [Dream] Output Parameters:

palette

The output is an RGBPalette object that contains the sampled colors from the input image. This palette can be used in subsequent nodes or processes to apply the extracted color scheme to other images or designs. The palette encapsulates the essence of the input image's colors, making it a valuable tool for color-based artistic and design tasks.

Sample Image as Palette [Dream] Usage Tips:

• To achieve a consistent color palette across multiple runs, use the same seed value.
• Experiment with different sample sizes to find the right balance between color diversity and simplicity for your project.
• Use high-quality images with a rich variety of colors to get the most out of the sampled palette.
