Atlantico focuses on a calm and consistent coding environment.
- Soft ocean-inspired palette
- Comfortable contrast for long sessions
- Unified editor and terminal ANSI colors
- Carefully tuned semantic highlighting
- Broad language support
- Low-noise UI design
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
