A coordinated VS Code theme family with deep indigo-black dark variants, purple-tinted light variants, high-contrast siblings, and optional bold or italic syntax styles. It is built for long technical sessions: calm contrast, semantic highlighting, and one consistent violet color language.

Highlights
12 shipped variants across dark, light, high-contrast dark, and high-contrast light profiles.
Base, bold, and italic styles for different typography preferences.
Purple-forward accents without neon noise.

Preview Settings
The screenshots use a ligature-ready editor setup. To get a similar look:
{
"editor.fontFamily": "'Fira Code', 'Montserrat', monospace",
"editor.fontLigatures": true,
"editor.fontWeight": "500",
"editor.lineHeight": 1.9,
"editor.letterSpacing": -0.2
}
The theme works with any font. These settings only tune the preview style.
