ComfyUI Node: 🔧 Mask From Color

🔧 Mask From Color+:

The MaskFromColor+ node is designed to create a mask from an image based on a specified color. This node is particularly useful for isolating specific areas of an image that match a given color, allowing you to perform further operations on those areas. By specifying the red, green, and blue values of the target color, along with a threshold to account for slight variations, you can generate a precise mask that highlights regions of the image that fall within the defined color range. This functionality is essential for tasks such as color-based segmentation, object detection, and image editing, where you need to focus on specific color regions within an image.

🔧 Mask From Color+ Input Parameters:

image

The image parameter is the input image from which the mask will be generated. This image should be in a format that the node can process, typically a tensor representing the image data.

red

The red parameter specifies the red component of the target color. It ranges from 0 to 255, with a default value of 255. This value determines the intensity of the red color that the node will use to create the mask.

green

The green parameter specifies the green component of the target color. It ranges from 0 to 255, with a default value of 255. This value determines the intensity of the green color that the node will use to create the mask.

blue

The blue parameter specifies the blue component of the target color. It ranges from 0 to 255, with a default value of 255. This value determines the intensity of the blue color that the node will use to create the mask.

threshold

The threshold parameter defines the tolerance level for color matching. It ranges from 0 to 127, with a default value of 0. This value allows for slight variations in the target color, making the mask generation more flexible and accommodating minor differences in color shades.

🔧 Mask From Color+ Output Parameters:

mask

The mask parameter is the output mask generated by the node. This mask is a binary image where the regions matching the specified color within the given threshold are highlighted. The mask can be used for further image processing tasks, such as segmentation or selective editing.

🔧 Mask From Color+ Usage Tips:

• To achieve a more accurate mask, ensure that the red, green, and blue values closely match the target color in the image.
• Adjust the threshold parameter to account for slight variations in the target color, especially if the image has gradients or lighting variations.
• Use the generated mask in combination with other nodes to perform complex image editing tasks, such as replacing the masked area with a different texture or color.

🔧 Mask From Color+ Common Errors and Solutions:

"Input image is not in the correct format"

• Explanation: The input image provided is not in a format that the node can process.
• Solution: Ensure that the input image is a tensor representing the image data and is correctly formatted.

"Threshold value out of range"

• Explanation: The threshold value provided is outside the acceptable range of 0 to 127. - Solution: Adjust the threshold value to be within the range of 0 to 127.

"Color values out of range"

• Explanation: The red, green, or blue values provided are outside the acceptable range of 0 to 255.
• Solution: Ensure that the red, green, and blue values are within the range of 0 to 255.
