🐳色彩范围:
The SelectiveColorNode is a powerful tool designed to allow you to make precise adjustments to specific color ranges within an image. This node is particularly beneficial for artists and designers who wish to enhance or modify the appearance of certain colors without affecting the entire image. By targeting specific hues, you can adjust the hue, saturation, and brightness of selected colors, providing a high degree of control over the final visual output. This capability is essential for tasks such as color correction, artistic effects, and creating visually striking images. The node's ability to focus on particular colors while leaving others untouched makes it an invaluable asset in any image processing workflow.
🐳色彩范围 Input Parameters:
image
This parameter represents the input image that you want to process. It is the base upon which all color adjustments will be applied. The image should be in a format compatible with the node's processing capabilities.
目标颜色
This parameter allows you to select the target color range you wish to adjust. Options include "红色", "黄色", "绿色", "青色", "蓝色", "品红", "白色", and "黑色". By choosing a specific color, you can focus the adjustments on that particular hue, enabling precise color manipulation.
色相偏移
This parameter controls the hue shift applied to the target color. It ranges from -180.0 to 180.0, with a default value of 0.0. Adjusting this value will change the hue of the selected color, allowing for creative color transformations.
饱和度调整
This parameter adjusts the saturation of the target color, with a range from -1.0 to 1.0 and a default value of 0.0. Increasing the value will make the color more vivid, while decreasing it will desaturate the color, potentially turning it into a grayscale.
明度调整
This parameter modifies the brightness of the target color, ranging from -1.0 to 1.0, with a default of 0.0. Positive values will lighten the color, while negative values will darken it, providing control over the color's luminance.
范围宽度
This parameter defines the width of the color range to be adjusted, with values between 10.0 and 90.0, and a default of 30.0. A wider range will include more hues around the target color, while a narrower range will focus the adjustment more precisely.
羽化程度
This parameter determines the feathering applied to the color adjustment, ranging from 0.0 to 1.0, with a default of 0.5. Feathering smooths the transition between adjusted and non-adjusted areas, creating a more natural blend.
🐳色彩范围 Output Parameters:
IMAGE
The output is an image that has undergone selective color adjustments based on the specified parameters. This processed image reflects the changes made to the target color range, showcasing the enhanced or modified hues, saturation, and brightness as defined by the input settings.
🐳色彩范围 Usage Tips:
- Experiment with the "色相偏移" parameter to achieve unique color effects, such as turning a red object into blue by shifting the hue.
- Use the "羽化程度" parameter to ensure smooth transitions between adjusted and non-adjusted areas, especially when working with complex images.
🐳色彩范围 Common Errors and Solutions:
Invalid color range
- Explanation: This error occurs when the specified "目标颜色" is not recognized by the node.
- Solution: Ensure that the "目标颜色" is one of the predefined options: "红色", "黄色", "绿色", "青色", "蓝色", "品红", "白色", or "黑色".
Image format not supported
- Explanation: The input image is in a format that the node cannot process.
- Solution: Convert the image to a compatible format, such as a standard RGB image, before inputting it into the node.
