LayerColor: ColorTemperature Node Documentation
Overview
The LayerColor: ColorTemperature node is part of the ComfyUI LayerStyle toolkit, which is designed to provide a range of post-processing effects for images. Specifically, this node adjusts the color temperature of an image, allowing users to fine-tune the warmth or coolness of the colors. This node can be an essential component for achieving specific aesthetic effects or correcting the white balance in images.
Inputs
The LayerColor: ColorTemperature node accepts the following inputs:
Image
- Type: Image
- Description: This input requires an image to be processed. The image should be in a compatible format that the ComfyUI system can handle, typically as a tensor format internally.
Temperature
- Type: Float
- Description: This input determines the degree of color temperature adjustment to be applied to the image. It accepts values ranging from -100 to 100.
- Default Value: 0
- Range:
- Negative Values: Apply cooler tones, shifting the image's colors towards blue.
- Positive Values: Apply warmer tones, enhancing red and orange hues in the image.
- Step: 1
Outputs
The node produces the following output:
Image
- Type: Image
- Description: The output is the image after the color temperature adjustment. This processed image can then be used in further workflow steps or exported as a final result.
Usage in ComfyUI Workflows
This node is particularly useful when integrated into workflows that require color correction or when aiming to achieve artistic styling through color temperature adjustments. Here are a few scenarios where this node might be especially beneficial:
- Post-Processing in Digital Art: Adjust the mood of illustrations or concept art by modifying the overall color warmth.
- Photography Adjustments: Correct the color balance in photos taken under unconventional lighting conditions.
- Video Game Textures: Refine textures used in gaming projects to ensure consistency across different lighting environments.
To use this node effectively:
- Connect the original image to the node's image input.
- Set the desired temperature value according to your color preferences.
- The output can then be further processed or saved as needed.
Special Features or Considerations
- Non-Destructive Adjustment: The operation is applied in a way that ensures the original image data is not lost, allowing users to revert or fine-tune adjustments easily.
- Real-Time Feedback: Adjustments can be made interactively with visual feedback, aiding in achieving the desired results promptly.
- Performance: Designed to process images efficiently, though performance may vary based on the input image size and the computing resources available.
- Limitations: Extreme adjustments (close to -100 or 100) may lead to unnatural results depending on the initial image characteristics.
This node enhances the flexibility and creativity options in ComfyUI, making it a valuable tool for users aiming to refine the visual aspects of their images efficiently.
