Themes in Replit allow you to customize the appearance of your workspace, from background colors and UI elements to syntax highlighting for your code. Personalize your development environment for better readability, reduced eye strain, and a more enjoyable coding experience.

​
Creating a custom theme

Follow these steps to create and customize your own theme:

  1. Navigate to your account page and scroll to the Themes section
  2. Select Create new theme
  3. Enter a title, select a color scheme (light or dark), and add an optional description
  4. Click Create Theme to open the Themes Editor

Global theme settings control the overall UI appearance:

  • Background: Sets the base color for most UI surfaces
  • Outline: Controls the color of borders and dividers
  • Foreground: Determines text and icon colors
  • Primary: Defines the color for buttons and interactive elements
  • Positive: Applies to success indicators like the Run button
  • Negative: Displays for errors and destructive action warnings

Click Apply Theme to start using your custom theme immediately.

​
Syntax highlighting

Customize how different code elements appear to improve readability and comprehension.

Proper syntax highlighting makes code easier to scan and understand at a glance. Choose colors that work well together and provide sufficient contrast against your background.

​
Theme design best practices

Create visually appealing and functional themes by following these guidelines:

​
Color and contrast

  • Balance contrast: Ensure sufficient difference between background and foreground elements
  • Create cohesive palettes: Choose colors that complement each other rather than clash
  • Maintain consistent brightness: Keep a similar brightness level across syntax elements
  • Design for accessibility: Consider users with visual impairments by avoiding low-contrast combinations

Common theme design issues to avoid:

  • Excessive brightness differences between syntax elements
  • Poorly matched colors that create visual discord
  • Insufficient contrast between code and background
