@colbyw/tailwind-color-inverter

A utility to invert TailwindCSS colors to auto generate colors for a dark theme.

It is intended to be used in conjunction with Tailwind and the theme-swapper plugin.

Usage

Visit the Tailwind playground for a simple demo.

// file: tailwind.config.js
const themeSwapper = require('tailwindcss-theme-swapper')
const defaultColors = require('tailwindcss/colors')
const invertColors = require('@colbyw/tailwind-color-inverter')

const lightTheme = {
    colors: {...defaultColors},
}

const darkTheme = {
    colors: invertColors(lightTheme.colors),
}

/** @type {import('tailwindcss').Config} */
module.exports = {
    content: ["./src/**/*.{html,js}"],
    plugins: [
        themeSwapper({
            themes: [
                {
                    name: 'base',
                    selectors: [':root'],
                    theme: lightTheme
                },
                {
                    name: 'dark',
                    selectors: ['.dark'],
                    theme: darkTheme,
                }
            ]
        })
    ]
}

Inspiration

This was inspired by nightwind, a Tailwind plugin that was never migrated to Tailwind v3.
