Finch's color scheme comes in two flavors: built-in themes and custom themes.
- Built-in themes: light, dark, and system — three fixed palettes, switchable any time in settings.
- Custom themes: a one-of-a-kind palette designed by Finch itself. Just describe the vibe you want in a sentence (e.g. "Morandi tones," "cyberpunk," "warm like a coffee shop"), and Finch designs a palette and applies it for you.
No color tweaking, no design skills required — just say what you want.
Three ways to set it
1. Switch a built-in theme in settings
Open Finch Settings → Appearance. The "Theme" row lets you click between light / dark / system, applied instantly.
2. Just ask Finch to design one
Describe the style you want in the chat box — click any of these to try it directly:
- [Design a Morandi-style light theme for me](finch://chat?message=Design a Morandi-style light theme for me)
- [Switch to a dark cyberpunk theme](finch://chat?message=Switch to a dark cyberpunk theme)
- [Give me a fresh, natural spring-morning light theme](finch://chat?message=Give me a fresh, natural spring-morning light theme)
- [Design a warm-white, soothing theme](finch://chat?message=Design a warm-white, soothing theme)
- [Switch me to an eye-friendly dark theme](finch://chat?message=Switch me to an eye-friendly dark theme)
Finch applies the design right away — if you don't love it, just say "try another one," "make it darker," or "use blue as the accent color" and it'll adjust. You can always switch back to the built-in light / dark / system themes too.
3. The "AI Custom Theme" entry in settings
The Finch Settings → Appearance page has an "AI Custom Theme" card. Click the palette icon next to it, and Finch opens a new conversation and sends the design request for you — same result as method 2, just without typing it yourself.
Tips
- Once a custom theme is applied, settings shows its name and a color-swatch preview, so you can review it or restore the default with one click.
- Want "a new palette every day"? Pair this with automation and have Finch switch themes every morning automatically — try: [Set up a daily task to change my theme every morning at 8am](finch://chat?message=Set up a daily task to change my theme every morning at 8am).
