Distance

What It Does

The Distance node measures the geometric distance between two colors in a specified color space. Unlike Delta E, which measures perceptual difference, this node calculates raw mathematical distance between color coordinates. The output is based on the CIEDE2000 color difference formula.

Inputs

Name	Description	Type	Required
Color A	First color for distance calculation	Color	No
Color B	Second color for distance calculation	Color	No
Precision	Number of decimal places in the result	Number	No
Space	Color space to perform calculation in (Lab, ICtCp, Jzazbz)	String	No

Outputs

Name	Description	Type
Value	The calculated distance between the colors	Number

How to Use It

1. Drag the Distance node into your graph.

2. Connect two colors to "Color A" and "Color B" inputs.

3. Select a color space (default is "Lab").

4. Set the desired precision for the result (default is 4 decimal places).

5. The output value indicates the geometric distance between the colors.

Tips

• Different color spaces produce different results as they represent color differently.

• Lab is generally a good default space for most design applications.

• Higher values indicate greater distance/difference between colors.
