# Batch Color DeltaE CIE76
|
|
## CIE2000 support planned for future
|
|
|
|
This is an implementation of the math on http://brucelindbloom.com for comparing
|
|
a large number of RGB pairs using the CIE76 standard. All credit for the math goes to
|
|
Bruce Lindbbloom and the Commission Internationale de l'Eclairage which defines the
|
|
standards.
|
|
|
|
This program is fairly straight forward to use, however it does not sanitize the csv
|
|
that you point it towards, so it is important to double check your files before use.
|
|
The csv format to use is three integer RGB values seperated with commas, and a return
|
|
character at the end of the line. This is the format output by google sheets when you
|
|
export to csv. Like so

The first RGB group on line 1 of the csv of the sample data set will be compared to
|
|
the first RGB group on line 1 of the csv of the reference data set.

|
{} In the RGBtoLab() function, the variable names in the XYZ to Lab section match the
|
|
variable names used on http://brucelindbloom.com/index.html?Eqn_RGB_XYZ_Matrix.html
|
|
to make the code implementation more legible.
