Themes, light and dark
Copy:Paste+ starts in the family Dark theme. Light is one click away.
Switch light and dark
Click the moon or sun button in the header of the toolbar panel or the settings page. From Dark it goes to Light; from Light, back to Dark.
Pick a theme
Open Settings → Appearance and choose a card under Theme. Each card previews its own colors.
The theme changes how the settings page, the toolbar panel and the copies window look. It changes nothing on the pages you paste into.
Put it back
Settings → Resets → Appearance returns to the default theme.
