How i can Use Color in TailWind CSS?.

Answer

Firstly we need to define colors object array in your custom theme
Define your custom color name into theme.colors
I am also explaining in a code,

const colors = require("tailwindcss/colors");

module.exports = {
purge: ["./src/**/*.{js,jsx,ts,tsx}", "./public/index.html"],
...
theme: {
...
colors: {
cadetblue: "#5f9ea0",
},
...
