Themes

1. ChatGPT

This theme provides a dynamic coloring based on your chosen color scheme.

Version 2.0.0 is a rewrite for the new ChatGPT design (October 2026). The whole palette is derived from one accent color per mode, so every surface, menu, border and text color follows it.

Options

All options are available in the Stylus style settings:

• Accent color (dark / light): the base color for each mode
• Background tint strength: from neutral gray (0) to the default tint (1) and beyond
• Tint text with the accent color: tinted or neutral text
• Sidebar: same as chat, darker or much darker
• OLED black background: pure black background in dark mode
• Dynamic user message color: colored user messages, or ChatGPT's native gray
• User message color: the accent color or a custom color
• Send and voice buttons: neutral or accent colored
• Chat width: default, wide, wider or full width
• Corner roundness: from square (0) to the default (1)
• Font family / Code font family: any installed font (native keeps ChatGPT's font)
• Hide: the disclaimer under the composer, the Chat / Work switch, the suggestions under the composer

Notes

• The theme overrides the colors from ChatGPT's Settings → Appearance (Theme, Accent, Background, Foreground, Contrast). Font size, Reduce motion and Diff markers still work as usual.
• Background tint strength and text tinting need a browser with CSS relative color support (Chrome 119+, Firefox 128+, Safari 16.4+).
• Only the logged-in ChatGPT is themed.
