The choice between dark mode and light mode has become a major design consideration for websites, apps, and software. Users are increasingly given the option to switch between these modes, and developers are left wondering: Which one offers the best user experience (UX)?
Both dark mode and light mode have their own advantages and disadvantages, and the right choice often depends on factors like accessibility, eye strain, energy efficiency, and personal preference. In this guide, we’ll explore the key differences, pros and cons, and when to use dark mode or light mode for the best UX.
1. What Is Dark Mode & Light Mode?
Dark Mode
Dark mode, also known as night mode or black theme, uses a dark background with light-colored text and elements. This mode is commonly seen in apps like Twitter, YouTube, and macOS and is designed to reduce eye strain in low-light environments.
🔹 Example Apps with Dark Mode:
Twitter
Instagram
Google Chrome
Facebook Messenger
Spotify
Light Mode
Light mode, also known as default mode, features a white or light-colored background with dark text. This is the traditional display setting used by most applications and websites.
🔹 Example Apps with Light Mode (by Default):
Google Search
LinkedIn
Facebook
Wikipedia
2. The Pros & Cons of Dark Mode vs. Light Mode
Dark Mode: Pros & Cons
