Choose a theme and customize its colors

Pick a theme

Meeting Tab Closer starts on Dark. Open Settings → Appearance and choose a card under Theme; each card previews its own colors. The sun and moon button, on the settings page and in the toolbar panel, switches between Light and the last dark theme you used.

Customize a theme's colors

The Customize card under Settings → Appearance edits the theme you're using. It has four colors — Background, Text, Buttons and Button text — with a preview and a readability line that warns when text drops below 4.5:1 (you can still save). The other colors — muted text, borders, hover and error — are worked out from those four so they stay readable.

Save to Customized saves your version under a Customized group in the theme picker and switches to it; the original never changes. Use the original colors puts the original's colors back in the editor, and Delete this version removes yours, so the original takes over. Your version paints the settings page and the toolbar panel.

Back up and put it back

A backup from Settings → Backup & Restore includes your theme and your customized themes. In Settings → Resets, the Appearance reset returns to the default theme, and the Customized themes row deletes your versions and leaves the originals unchanged; if you're using one of yours, its original takes over. Reset all clears them too.
