# Appearance & theming

V3Code's look is yours to set, right from Settings. No hunting for a theme extension: the color picker is built in.

## Theme Builder

Open **Settings → Theme Builder** and every part of the editor UI is a color you can pick. Changes apply **live** as you go. It's grouped so you're not staring at a wall of swatches:

- **Accent** — Focus/accent (focus rings + primary accent), Links, Badge, Button, Progress/usage.
- **Surfaces** — Editor, Sidebar, Bottom panel, Activity bar, Title bar, Status bar, Active tab, Inputs.
- **Text & borders** — Text (primary UI text), Muted text (secondary), Borders (separators).

Each swatch opens a full picker (hex or RGB). **Reset** puts it back to default.

> Note:
>
> On the built-in grey V3Code themes, some surfaces and accents are managed by the app chrome, so your custom colors apply best on top of another base theme.

## Venom animations

V3Code shows a subtle **venom-green motion** while the agent works — the composer beam, the sticky-capsule "snake," and accent glows. It's on by default.

Prefer calm? Turn **Venom animations** off in Settings for grey-only chrome. It's recommended if flashing or motion bothers you, and your OS **Reduce motion** setting turns it off automatically.
