ComfyUI Node: LayerUtility: HSV Value

LayerUtility: HSV Value:

The LayerUtility: HSV Value node is designed to convert a given color value into its corresponding HSV (Hue, Saturation, Value) components. This node is particularly useful for AI artists who need to manipulate or analyze colors in their projects. By converting colors to the HSV color space, you can more easily adjust the hue, saturation, and brightness of an image, which can be more intuitive than working directly with RGB values. This node supports input in both hexadecimal string format and RGB tuple format, making it versatile for various use cases. The primary goal of this node is to provide a straightforward method to decompose a color into its HSV components, enabling more precise and creative control over color adjustments.

LayerUtility: HSV Value Input Parameters:

color_value

The color_value parameter accepts the color input that you want to convert to HSV. This parameter can be provided either as a hexadecimal string (e.g., "#FF5733") or as an RGB tuple (e.g., (255, 87, 51)). The input type determines how the node processes the color value. If a hexadecimal string is provided, it is directly converted to HSV. If an RGB tuple is provided, it is first converted to a hexadecimal string and then to HSV. This flexibility allows you to use the format that best suits your workflow.

LayerUtility: HSV Value Output Parameters:

H

The H output parameter represents the Hue component of the color in the HSV color space. Hue is an angle in degrees (0-360) that represents the color type, such as red, green, or blue. This value helps you understand the basic color category of the input color.

S

The S output parameter represents the Saturation component of the color in the HSV color space. Saturation is a percentage (0-100) that indicates the intensity or purity of the color. A higher saturation value means the color is more vivid, while a lower value means it is more washed out or gray.

V

The V output parameter represents the Value (or brightness) component of the color in the HSV color space. Value is a percentage (0-100) that indicates how bright the color is. A higher value means the color is closer to white, while a lower value means it is closer to black.

LayerUtility: HSV Value Usage Tips:

• Use the color_value parameter in hexadecimal format for quick and easy color input, especially if you are working with web colors or color pickers.
• When working with RGB tuples, ensure the values are within the 0-255 range to avoid errors and ensure accurate conversion.
• Utilize the HSV components to make intuitive adjustments to your colors, such as changing the hue to shift the color family or adjusting the saturation to make the color more or less intense.

LayerUtility: HSV Value Common Errors and Solutions:

LayerUtility: HSV Value: color_value input type must be tuple or string.

• Explanation: This error occurs when the color_value parameter is not provided as either a hexadecimal string or an RGB tuple.
• Solution: Ensure that the color_value parameter is correctly formatted as either a hexadecimal string (e.g., "#FF5733") or an RGB tuple (e.g., (255, 87, 51)).

Invalid Hex Code in <color_value>

• Explanation: This error occurs when the provided hexadecimal string is not in a valid format.
• Solution: Check that the hexadecimal string starts with a "#" followed by six hexadecimal digits (e.g., "#FF5733"). Ensure there are no extra characters or spaces.
