What’s the Difference Between Dark Mode and Light Mode on Websites

In the digital age, the visual design of websites is not just about aesthetics but also about user experience and comfort. Two popular design schemes that have become a staple in user interface (UI) design are dark mode and light mode. Each mode offers distinct advantages and can significantly impact the way users interact with websites.

Dark Mode

Dark mode, also known as night mode, features a dark color scheme predominantly using shades of black and gray. It’s designed to reduce the light emitted by device screens while maintaining the minimum color contrast ratios required for readability.


  1. Reduced Eye Strain: Dark mode can be easier on the eyes, especially in low-light environments, as it reduces the amount of bright light emitted.
  2. Energy Efficiency: On devices with OLED or AMOLED screens, dark mode can save battery life since these screens use less power to display darker colors.
  3. Aesthetics: Many users prefer dark mode for its sleek and modern appearance.


  1. Contrast and Readability: In some cases, dark mode can make reading text more challenging, especially for longer content or for users with certain visual impairments.
  2. Limited Situational Use: Dark mode may not be ideal in well-lit conditions as it can create glare, making it harder to read.

Light Mode

Light mode, the traditional design choice, features a light background, typically white, with dark-colored text. This mode is standard across most websites and operating systems.


  1. Readability: Light mode often provides better contrast between background and text, improving readability, especially in well-lit environments.
  2. Familiarity and Accessibility: Being the default mode for many years, light mode is more familiar to a wider range of users and can be more accessible to users with specific visual impairments.
  3. Consistency: Light mode offers a more consistent look across different websites and platforms.


  1. Eye Strain: Bright screens can cause more eye strain, particularly in darker environments or during prolonged use.
  2. Power Consumption: Light mode can consume more battery life on OLED and AMOLED screens.

User Preference and Context

The choice between dark and light mode often boils down to personal preference and situational context. Some users switch between modes based on the time of day or ambient lighting, while others stick to one mode based on their comfort and aesthetic preferences.

Both dark mode and light mode have their unique advantages and drawbacks. The choice between them should be informed by the user’s needs, the environment in which they are using the device, and personal comfort levels. As technology and design preferences evolve, we may see more adaptive and customizable options that cater to a broader range of user preferences and needs.
