ComfyUI Node: 😼> RGB Color

😼> RGB Color:

The > RGB Color node is designed to manipulate and adjust RGB color values in a precise and controlled manner. This node allows you to input specific red, green, and blue values, and then apply a modification factor to adjust the overall color intensity. The node ensures that the resulting color values remain within the valid range for RGB colors (0 to 255) and provides the output in both integer and hexadecimal formats. This functionality is particularly useful for AI artists who need to fine-tune colors in their digital artworks, ensuring consistency and accuracy in color representation.

😼> RGB Color Input Parameters:

red

The red parameter specifies the intensity of the red component in the RGB color. It accepts values ranging from 0 to 255, where 0 represents no red and 255 represents the maximum intensity of red. Adjusting this parameter will affect the overall hue and brightness of the resulting color.

green

The green parameter specifies the intensity of the green component in the RGB color. It accepts values ranging from 0 to 255, where 0 represents no green and 255 represents the maximum intensity of green. Modifying this parameter will influence the color's hue and brightness.

blue

The blue parameter specifies the intensity of the blue component in the RGB color. It accepts values ranging from 0 to 255, where 0 represents no blue and 255 represents the maximum intensity of blue. Changing this parameter will alter the hue and brightness of the resulting color.

plus_minus

The plus_minus parameter is used to adjust the overall intensity of the RGB color. It can accept both positive and negative values, where positive values increase the intensity and negative values decrease it. The node ensures that the resulting color values remain within the valid range (0 to 255) by calculating the effective adjustment based on the input ratios.

😼> RGB Color Output Parameters:

color

The color parameter provides the resulting RGB color as a single integer value. This value is a combination of the red, green, and blue components, making it easy to use in various applications that require a single color value.

new_r

The new_r parameter represents the adjusted intensity of the red component after applying the plus_minus modification. It ensures that the value remains within the range of 0 to 255.

new_g

The new_g parameter represents the adjusted intensity of the green component after applying the plus_minus modification. It ensures that the value remains within the range of 0 to 255.

new_b

The new_b parameter represents the adjusted intensity of the blue component after applying the plus_minus modification. It ensures that the value remains within the range of 0 to 255.

hex_color

The hex_color parameter provides the resulting RGB color in hexadecimal format. This is useful for web design and other applications where colors are often represented in hex code.

😼> RGB Color Usage Tips:

• To achieve a balanced color adjustment, ensure that the red, green, and blue values are proportionate to the desired hue before applying the plus_minus modification.
• Use the hex_color output for easy integration with web design projects, as it provides a standard color representation.

😼> RGB Color Common Errors and Solutions:

Invalid color value

• Explanation: This error occurs when the input values for red, green, or blue are outside the valid range of 0 to 255. - Solution: Ensure that all input values for red, green, and blue are within the range of 0 to 255.

Division by zero

• Explanation: This error can occur if the sum of the red, green, and blue values is zero, leading to a division by zero when calculating ratios.
• Solution: Ensure that at least one of the red, green, or blue values is greater than zero to avoid division by zero.
