A tailwind.config.js file with the full color palette of Tailwind CSS 2.0, which I couldn't find available elsewhere. As of 2020-12-22, this config file works properly. Note that it will significantly increase the bundle size of your unpurged tailwind.css file!

tailwind.config.js

// NOTE: AS REQUESTED, TAILWIND CSS 3.0 HAS FULL SUPPORT FOR ALL COLORS BY DEFAULT
// SEE https://tailwindcss.com/blog/tailwindcss-v3#every-color-out-of-the-box.

// As of 2020-12-22, this tailwind.config.js file includes all colors
// from the Tailwind CSS color palette reference laid out in full at this
// link: https://tailwindcss.com/docs/customizing-colors#color-palette-reference.
// Note that this will increase your unpurged Tailwind CSS file size immensely,
// for me it went from 3.64MB to 7.62MB! Be sure to purge your CSS in production!

// First we import the tailwindcss/colors dependency, as referenced
// here: https://tailwindcss.com/docs/customizing-colors#curating-colors
const colors = require("tailwindcss/colors");

module.exports = {
  purge: ["./**/*.html", "./**/*.js"],
  darkMode: false,
  theme: {
    extend: {},
    colors: {
      // Now we build the full color palette, using all colors available
      // as shown at this link: https://tailwindcss.com/docs/customizing-colors#color-palette-reference
