Customize VS Code in 2026: Themes, Icons & UI Tweaks

Visual Studio Code (VS Code) is popular because it stays lightweight while covering most daily development needs. A few visual tweaks can improve readability, reduce friction, and help you move faster in large projects.

Customization in 2026 is not only about style. It is also a practical way to make your workspace consistent across devices and easier to navigate.

Where customization lives in VS Code

Most appearance changes are controlled through Settings and can be applied at two levels: User settings (for everything) and Workspace settings (for the current project only).

Open Settings with Ctrl + , (Windows/Linux) or Cmd + , (macOS). When you want more control, open settings.json and edit values directly.

Rule of thumb

Use User settings for fonts, layout, and your default theme. Use Workspace settings for project-specific preferences and per-project UI colors.

Icon themes

Make the file explorer easier to scan. VS Code lets you replace default file and folder icons with an icon theme. This can make big codebases easier to read at a glance, especially with many file types.

Install the Material Icon Theme extension

1. Open the Extensions view: Ctrl + Shift + X / Cmd + Shift + X
2. Search for Material Icon Theme
3. Click Install

To enable it:

1. Open the Command Palette: Ctrl + Shift + P / Cmd + Shift + P
2. Run: Preferences: File Icon Theme
3. Select: Material Icon Theme

Optional: product icon themes

If you want to change icons in the VS Code interface (Activity Bar icons and UI icons):

1. Open the Command Palette
2. Run: Preferences: Product Icon Theme
3. Pick the theme you prefer

Color themes: choose a theme you can read for hours

A good theme keeps syntax highlighting readable without becoming noisy. VS Code includes built-in themes, and the Marketplace adds thousands more.

Install the Night Owl theme (popular dark option)

1. Open Extensions
2. Search for Night Owl
3. Click Install

To enable it:

1. Open the Command Palette
2. Run: Preferences: Color Theme
3. Select: Night Owl

If you prefer built-in options, try Dark+ or Light+. If you have eyestrain issues, consider a high-contrast variant and increase font size.

Distinguish projects with Peacock

If you keep multiple VS Code windows open, it is easy to edit the wrong project. The Peacock extension helps by coloring the VS Code frame per workspace.

Install Peacock and set a workspace color

1. Open Extensions and install Peacock
2. Open the Command Palette
3. Run: Peacock: Enter a Color
4. Paste a hex color value, for example: #2D2A55.

Tip: Save the color in Workspace Settings so each project keeps its own visual identity.

Practical readability tweaks (no extensions required)

These settings usually make a bigger difference than another theme. Use Settings search, or paste these keys into your settings.json.

Readability

• editor.fontSize: increase text size
• editor.lineHeight: add breathing room between lines
• editor.fontLigatures: enable if your font supports it
• editor.minimap.enabled: disable the minimap to reduce visual clutter

Navigation and context

• breadcrumbs.enabled: quick navigation across folders and symbols
• editor.stickyScroll.enabled: keep context visible while scrolling
• editor.guides.indentation: show indentation guides for structure

Example settings.json snippet

{
  "editor.fontSize": 14,
  "editor.lineHeight": 22,
  "editor.fontLigatures": true,
  editor. Minimap. enabled": false,
  "breadcrumbs.enabled": true,
  editor.stickyScroll.enabled": true
}

Save, share, and switch setups

If you code on more than one machine, two features help keep your editor consistent: Settings Sync and Profiles.

Settings Sync can sync settings, keybindings, and extensions when you sign in. Profiles let you keep separate bundles of settings and extensions, for example, learning vs work.

Troubleshooting: revert changes fast

When something looks wrong, start with quick resets.

• Run Preferences: Color Theme and switch back to a default theme
• Run Preferences: File Icon Theme to revert icons
• Disable extensions one by one to find conflicts
