I'm trying to generate random hexadecimal colors between this range: min= #00FF00 (green) and max= #FF0000 (red).

What I have tried:

I made my own search but I found only how to generate random hexadecimal colors not between two hexadecimal values (min and max).

If you're going to derive your colors from ARGB, it's intuitively simpler to work with the 2 colors individually; and using integers.

public static System.Drawing.Color FromArgb (int alpha, int red, int green, int blue);

Generate a random number between 65280 (0x00ff00) and 16711680 (0xff0000).
Math.random() - JavaScript | MDN[^]

JavaScript

function getRandomInt(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min) + min); //The maximum is exclusive and the minimum is inclusive
}

const minValue = 0x00ff00;
const maxValue = 0xff0000;
let randomValue = getRandomInt(minValue, maxValue + 1);

Convert that number to hexadecimal:
