ComfyUI Node: Image Rotate Hue

Image Rotate Hue:

The Image Rotate Hue node is designed to adjust the hue of an image, effectively shifting the colors in a circular manner around the color wheel. This node is particularly useful for AI artists looking to experiment with color variations and achieve unique visual effects without altering the image's brightness or saturation. By rotating the hue, you can transform the overall color scheme of an image, making it a powerful tool for creative color adjustments and artistic exploration.

Image Rotate Hue Input Parameters:

image

This parameter accepts the image you want to adjust. The image should be in a compatible format that the node can process, typically a tensor representation of an image.

hue_shift

This parameter controls the degree of hue rotation applied to the image. It accepts a floating-point value between 0.0 and 1.0, where 0.0 means no change and 1.0 represents a full 360-degree rotation around the color wheel. The default value is 0.0, meaning no hue shift. Adjusting this value will change the colors in the image while maintaining their original brightness and saturation.

Image Rotate Hue Output Parameters:

IMAGE

The output is the adjusted image with the hue rotated according to the specified hue_shift parameter. This image is returned in a tensor format, ready for further processing or display.

Image Rotate Hue Usage Tips:

• Experiment with small increments in the hue_shift parameter to find subtle color variations that enhance your image.
• Use this node in combination with other color adjustment nodes to achieve complex and visually appealing effects.
• Remember that a hue_shift of 1.0 will bring the colors back to their original state, as it represents a full rotation around the color wheel.

Image Rotate Hue Common Errors and Solutions:

The hue_shift 'X' is out of range. Valid range is 0.0 - 1.0

• Explanation: This error occurs when the hue_shift parameter is set to a value outside the valid range of 0.0 to 1.0.
• Solution: Ensure that the hue_shift value is within the specified range. Adjust the value to be between 0.0 and 1.0.

Invalid image format

• Explanation: This error occurs if the input image is not in a compatible format that the node can process.
• Solution: Convert the image to a tensor format before passing it to the node. Use appropriate image conversion functions if necessary.
