✨ Why Atlantico?

Most dark themes are built for visual impact. Atlantico was built for endurance.

Designed for developers with astigmatism, eye strain, or light sensitivity, every colour decision in Atlantico was made to reduce fatigue without sacrificing readability. The palette avoids oversaturated neons and harsh whites in favour of soft, ocean-inspired tones that your eyes can rest on for hours.

• Low visual noise — muted backgrounds, subtle UI chrome, nothing competing for attention
• Calibrated contrast — readable without being aggressive
• Semantic colour logic — consistent token roles across all languages, so your brain learns the pattern once
• Unified experience — editor and integrated terminal share the same palette, keeping the environment visually coherent

Whether you code for 2 hours or 10, Atlantico is designed to stay comfortable.

1. Open VS Code
2. Go to Extensions (Ctrl+Shift+X)
3. Search for Atlantico

💡 Recommended Settings

For the best experience alongside Atlantico:

{
  "editor.fontFamily": "'JetBrains Mono', 'Fira Code', monospace",
  "editor.fontSize": 14,
  "editor.lineHeight": 1.5,
  "editor.fontLigatures": true,
  "editor.cursorBlinking": "smooth",
  "editor.renderLineHighlight": "line",
  "workbench.colorTheme": "Atlantico"
}

A monospace font with ligatures pairs especially well with Atlantico's operator and punctuation colouring.
