Gloam — Dark Theme for Claude Design

Dark theme for Claude Design native panels. The design preview stays untouched. Toggle on/off from the toolbar.

Gloam gives the Claude Design tool (claude.ai/design) a dark theme that matches Claude's own warm-charcoal palette — while leaving the design preview you're working on pixel-for-pixel untouched. What it does: - Darkens only the interface — chat, header, tabs, cards and toolbars. The cross-origin design preview is never modified. - Value-based, not selector-based — it remaps the page's own colors, so it keeps working across Claude's frequent UI updates. - One-click toggle from the toolbar. Turn it off and the page is left exactly as it was. Privacy: the only permission requested is "storage", used solely to remember the on/off state. Nothing is collected or sent anywhere.
