Paint with numbers with Adobe Illustrator Javascript

Hello thanks to moluapple, I got this script from the adobe support community, I'm a beginner in javascript but I have a task to make, I have to paint numbers in each color of the image, actually, I see that in this solution brings me numbers in each layer, but doesn't work for the colors, can someone has a similar solution?

Let me add the expected result which is for each color on the picture the script adds a number to the color 1 for green 2 for yellow etc, let me show you.enter image description here

here is the original link
