Colors¶

Void uses a token-based color system. Every color is a CSS custom property on :root, making the palette easy to override or extend.

Core tokens¶

Ink¶

The page background. Pure black — NothingOS signature.

--void-ink: #000000;

Text hierarchy¶

--void-text-primary: #ffffff;
--void-text-secondary: rgba(255, 255, 255, 0.7);
--void-text-muted: #555555;
--void-text-accent: #ff3030;

Ghost¶

Semi-transparent whites used for borders, dividers, and subtle surfaces.

--void-ghost: rgba(255, 255, 255, 0.06);
--void-ghost-strong: rgba(255, 255, 255, 0.12);

Accent¶

The primary interactive color — Nothing Red.

--void-accent: #ff3030;
--void-accent-dim: rgba(255, 48, 48, 0.15);
--void-accent-glow: rgba(255, 48, 48, 0.3);

Glass¶

Background colors for glass panels:

--void-glass-bg: rgba(255, 255, 255, 0.08);
--void-glass-bg-strong: rgba(255, 255, 255, 0.15);
--void-glass-border: rgba(255, 255, 255, 0.18);
--void-glass-border-strong: rgba(255, 255, 255, 0.35);

Accent color¶

Void uses a single accent color — Nothing Red (#ff3030). It is used sparingly for interactive elements, focus states, and accent signals.

Token	Hex	Usage
`--void-accent`	`#ff3030`	Primary accent
`--void-accent-dim`	`rgba(255, 48, 48, 0.15)`	Faint accent backgrounds
`--void-accent-glow`	`rgba(255, 48, 48, 0.3)`	Glow effects

Shadows¶

--void-shadow-sm: 0 1px 2px rgba(0, 0, 0, 0.3);
--void-shadow-md: 0 4px 12px rgba(0, 0, 0, 0.4);
--void-shadow-lg: 0 8px 32px rgba(0, 0, 0, 0.5);
--void-shadow-glass: 0 8px 32px rgba(0, 0, 0, 0.3), inset 0 1px 0 rgba(255, 255, 255, 0.1);

Overriding colors¶

Override any token in your custom.css:

:root {
  --void-accent: #818cf8;
  --void-ink: #050510;
}

Add it to mkdocs.yml:

extra_css:
  - stylesheets/custom.css

Tip

Use the browser DevTools to inspect :root and find the exact token name you want to override. All tokens are prefixed with --void-.

Light mode¶

When the palette scheme is set to "default", the token values flip to their light-mode equivalents:

[data-md-color-scheme="default"] {
  --void-ink: #ffffff;
  --void-text-primary: #000000;
  --void-text-secondary: rgba(0, 0, 0, 0.7);
  --void-text-muted: #aaaaaa;
  --void-ghost: rgba(0, 0, 0, 0.04);
  --void-ghost-strong: rgba(0, 0, 0, 0.08);
  --void-glass-bg: rgba(0, 0, 0, 0.05);
  --void-glass-bg-strong: rgba(0, 0, 0, 0.1);
  --void-glass-border: rgba(0, 0, 0, 0.12);
  --void-glass-border-strong: rgba(0, 0, 0, 0.25);
}

Warning

Glass effects are less visible in light mode. Consider reducing blur intensity when using the light scheme.
