We tried using the solution provided in the below link provided by @Emeeus. Link: Illustrator script to find all colors in document

We opened the SVG file in a empty web page and ran the below code in the Console:

var doc = document.getElementsByTagName("*");
               var colors = [];

               for (let j = 0; j < doc.length; j++) {

               var styles = window.getComputedStyle(doc[j], null)

               for (let i = 0; i < styles.length; i++) {

if (typeof styles[styles[i]] !== "undefined" && styles[styles[i]].match(/rgb\([0-9, ]*\)/g)) {

let color = styles[styles[i]].replace(/(.*)(rgb\([0-9, ]*\))(.*)/g,"$2")
  if (!colors.includes(color))
    colors.push(color);

}

 }

  }
 console.log(colors)

It does give you the list of color codes used in the file. But there are more 2 requirements we need:

1. The color code is in RBG form, we require the same in HEX code.
2. The count of each color code is not extracted in the output.
