ComfyUI Node: 🎨 Palette Color Shift

Palette Color Shift [Dream]:

The Palette Color Shift [Dream] node is designed to modify the color balance of an image palette by applying specific multipliers to the red, green, and blue channels. This node allows you to fine-tune the color composition of your image, making it possible to achieve a desired aesthetic or correct color imbalances. By adjusting the multipliers, you can enhance or diminish the intensity of each color channel, providing a high degree of control over the final appearance of your image. This node is particularly useful for AI artists looking to experiment with color dynamics and achieve unique visual effects in their artwork.

Palette Color Shift [Dream] Input Parameters:

red_multiplier

The red_multiplier parameter adjusts the intensity of the red channel in the image palette. Increasing this value will enhance the red tones, while decreasing it will reduce them. This parameter accepts a floating-point number with a default value of 1.0, a minimum value of 0.0, and a maximum value of 100.0. Adjusting this parameter can significantly impact the warmth and vibrancy of the image.

green_multiplier

The green_multiplier parameter controls the intensity of the green channel in the image palette. A higher value will amplify the green tones, whereas a lower value will diminish them. This parameter accepts a floating-point number with a default value of 1.0, a minimum value of 0.0, and a maximum value of 100.0. Modifying this parameter can affect the natural and earthy feel of the image.

blue_multiplier

The blue_multiplier parameter influences the intensity of the blue channel in the image palette. Increasing this value will boost the blue tones, while decreasing it will lessen them. This parameter accepts a floating-point number with a default value of 1.0, a minimum value of 0.0, and a maximum value of 100.0. Adjusting this parameter can alter the coolness and depth of the image.

fixed_brightness

The fixed_brightness parameter determines whether the brightness of the image should remain constant during the color shift process. It accepts two options: "yes" or "no". Selecting "yes" will maintain the overall brightness, ensuring that the image does not become too dark or too bright as a result of the color adjustments. Choosing "no" allows the brightness to vary based on the applied multipliers.

Palette Color Shift [Dream] Output Parameters:

palette

The palette output parameter returns the modified RGB palette after applying the specified color multipliers. This output is crucial for understanding the impact of the adjustments made to the red, green, and blue channels. The resulting palette can be used to further refine the image or as a reference for achieving consistent color schemes across multiple artworks.

Palette Color Shift [Dream] Usage Tips:

• Experiment with different multiplier values to achieve a wide range of color effects, from subtle enhancements to dramatic shifts.
• Use the fixed_brightness option to maintain consistent brightness levels, especially when making significant color adjustments.
• Combine this node with other color manipulation nodes to create complex and visually appealing color compositions.

Palette Color Shift [Dream] Common Errors and Solutions:

"Invalid multiplier value"

• Explanation: This error occurs when one of the multiplier values is set outside the allowed range (0.0 to 100.0).
• Solution: Ensure that all multiplier values are within the specified range and try again.

"Palette input is empty"

• Explanation: This error happens when the input palette is not provided or is empty.
• Solution: Verify that a valid RGB palette is connected to the node before executing the process.

"Unexpected data type for palette"

• Explanation: This error indicates that the input provided is not of the expected RGB palette type.
• Solution: Check that the input is correctly formatted as an RGB palette and that it matches the expected data type.
