✨ Why Atlantico?

Atlantico was designed for developers who prefer a calmer coding environment, especially during long sessions.

The palette avoids harsh whites, intense neon tones, and strong UI distractions. Instead, it uses soft contrast, muted surfaces, and consistent syntax colors to keep code readable without making the editor feel visually aggressive.

Atlantico is built around a few core principles:

Visual calm, the interface should not compete with the code
Readable contrast, text should stay clear without becoming harsh
Semantic consistency, similar token roles should feel familiar across languages
Unified experience, the editor and integrated terminal should feel like one environment

💡 Recommended Settings

For the best experience with 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 well with Atlantico's balanced operator colors and low-noise punctuation styling.
