ComfyUI Node: LayerColor: ColorTemperature

LayerColor: ColorTemperature:

The LayerColor: ColorTemperature node is designed to adjust the color temperature of an image, which can significantly alter the mood and visual appeal of your artwork. By modifying the color temperature, you can make an image appear warmer or cooler, enhancing the overall aesthetic and emotional impact. This node is particularly useful for AI artists looking to fine-tune the color balance of their creations, ensuring that the final output aligns with their artistic vision. The node works by adjusting the red, green, and blue channels of the image based on the specified temperature value, providing a flexible and powerful tool for color correction and enhancement.

LayerColor: ColorTemperature Input Parameters:

image

The image parameter is the input image that you want to adjust. This image should be in a tensor format, typically with dimensions representing batch size, height, width, and color channels. The image serves as the canvas on which the color temperature adjustments will be applied.

temperature

The temperature parameter controls the degree of color temperature adjustment. A positive value will make the image appear warmer by enhancing the red and green channels, while a negative value will make it cooler by enhancing the blue channel. The temperature value is divided by -100 to scale the adjustments appropriately. There is no strict minimum or maximum value, but typical values range from -100 to 100 for noticeable effects.

LayerColor: ColorTemperature Output Parameters:

result

The result parameter is the output image after the color temperature adjustment has been applied. This image will have the same dimensions as the input image but with modified color channels based on the specified temperature value. The result is returned as a tensor, ready for further processing or final output.

LayerColor: ColorTemperature Usage Tips:

• Experiment with different temperature values to find the perfect balance for your image. Small adjustments can make a significant difference.
• Use positive temperature values to create a warm, inviting atmosphere in your image, ideal for sunset scenes or cozy indoor settings.
• Use negative temperature values to create a cool, calm atmosphere, perfect for winter scenes or modern, minimalist designs.

LayerColor: ColorTemperature Common Errors and Solutions:

"Input image must be a tensor."

• Explanation: This error occurs if the input image is not in the expected tensor format.
• Solution: Ensure that your input image is correctly formatted as a tensor with dimensions representing batch size, height, width, and color channels.

"Temperature value out of range."

• Explanation: This error occurs if the temperature value is excessively high or low, leading to unrealistic color adjustments.
• Solution: Use temperature values within a reasonable range, typically between -100 and 100, to achieve natural-looking results.

"Processed image(s) not returned."

• Explanation: This error occurs if the node fails to return the processed image.
• Solution: Check the node's implementation to ensure that the result is correctly computed and returned. Ensure that the input image and temperature parameters are valid.
