Atlantu Color Theme
Atlantu is a personal dark theme for Visual Studio Code, modified from
One Dark Pro.
It pairs a Darcula-shaped editor shell with Atlantu's own high-saturation code
palette. The workbench uses low-contrast dark surfaces and translucent layers,
while syntax colors stay direct and easy to distinguish in dense code.
Design Philosophy
Atlantu separates place from meaning. The workbench should recede into a quiet
Darcula-style frame; identifiers, declarations, and member access should carry
the visual weight.
- Editor, terminal, sidebar, tabs, and widgets share a compact dark base.
- Tabs, status chrome, gutters, and list states use low-opacity overlays instead
of large blocks of new color.
- Syntax colors are intentionally saturated so functions, variables, fields,
types, and constants can be scanned quickly.
- Semantic highlighting is part of the identity: local variables, global
variables, parameters, properties, and enum members keep distinct colors.
- Warm amber accents are reserved for actions and small UI signals, so they
remain recognizable without taking over the editor.
- The theme is Darcula-inspired rather than a strict port; Atlantu keeps its
brighter semantic palette on top of the darker shell.
Style
- Darcula-style dark backgrounds for the editor, sidebar, tabs, widgets, and
terminal.
- Warm amber accents for buttons, active tab borders, badges, and remote status.
- Blue selection and low-contrast focus colors that stay visible on dark
surfaces.
- High-contrast syntax colors for quick scanning across dense code.
- Muted comments, line numbers, whitespace, gutters, and inactive chrome.
- Semantic highlighting enabled for variables, parameters, properties, and enum
members.
Syntax Palette
- Functions: orange.
- Keywords and macros: soft purple.
- Local variables: light blue.
- Parameters: clear blue.
- Properties and enum members: green.
- Types and classes: cyan-green.
- Strings: warm peach.
- Numbers: pale blue.
- Comments: neutral gray.
The theme includes extra TextMate scope tuning for JSON, Markdown, Makefile,
PowerShell, TypeScript/JavaScript, XML, and CSS.
