ComfyUI Node: COLOR BLIND (JOV) 👁‍🗨

COLOR BLIND (JOV) 👁‍🗨:

Use the Color Blind Node to simulate color blindness effects on images. You can select various types of color deficiencies, adjust the severity of the effect, and apply the simulation using different simulators. This node is ideal for accessibility testing and design adjustments, ensuring inclusivity in your visual content.

COLOR BLIND (JOV) 👁‍🗨 Input Parameters:

PIXEL

This parameter accepts the image data that you want to process. It can handle various image types, making it versatile for different input formats.

DEFICIENCY

This parameter allows you to select the type of color deficiency to simulate. Options include different types of color blindness such as Protanopia, Deuteranopia, and Tritanopia. The default value is PROTAN. This selection impacts how the colors in the image are altered to reflect the chosen color deficiency.

SIMULATOR

This parameter lets you choose the simulator to use for the color blindness effect. Options include AUTOSELECT, BRETTEL1997, COBLISV1, COBLISV2, MACHADO2009, VIENOT1999, and VISCHECK. The default value is AUTOSELECT. Each simulator uses a different algorithm to simulate color blindness, affecting the final appearance of the image.

VALUE

This parameter controls the severity of the color blindness effect, ranging from 0 to 1. The default value is 1, which represents the full effect. Adjusting this value allows you to fine-tune the intensity of the simulation.

COLOR BLIND (JOV) 👁‍🗨 Output Parameters:

RI

The red channel of the processed image, reflecting the simulated color blindness effect.

GI

The green channel of the processed image, reflecting the simulated color blindness effect.

BI

The blue channel of the processed image, reflecting the simulated color blindness effect.

MI

The mask channel of the processed image, if applicable, reflecting the simulated color blindness effect.

COLOR BLIND (JOV) 👁‍🗨 Usage Tips:

• Use the DEFICIENCY parameter to test how your designs appear to individuals with different types of color blindness.
• Adjust the VALUE parameter to see how varying levels of color blindness severity affect your image.
• Experiment with different SIMULATOR options to find the one that best represents the color blindness effect you want to simulate.

COLOR BLIND (JOV) 👁‍🗨 Common Errors and Solutions:

"Invalid image format"

• Explanation: The input image format is not supported.
• Solution: Ensure that the input image is in a supported format such as BGRA or convert it to a compatible format before processing.

"Unknown deficiency type"

• Explanation: The specified color deficiency type is not recognized.
• Solution: Verify that the DEFICIENCY parameter is set to one of the supported types like PROTAN, DEUTERAN, or TRITAN.

"Simulator not found"

• Explanation: The specified simulator is not available.
• Solution: Check that the SIMULATOR parameter is set to a valid option such as AUTOSELECT, BRETTEL1997, or MACHADO2009.
