Light and dark theme
Android · iPhone · quillo.trUpdated:
Switch between night and day with one tap: the moon icon makes everything dark (the app and the pages in the reader together), the sun icon switches back to light. On tablets the button is in the same place on the library, folders, the reader, Settings, Tools, Help and the scanner; in short, on every screen with the Ai orb. On phones, to keep the top bar uncluttered, it is the "Night mode" / "Day mode" row in the ⋮ menu. Your choice is saved to the Theme setting and carries over to the web with your account.
By default follows the phone's theme: in light theme the background is off-white (#F5F6F4) with white cards; in dark theme the background is dark navy, cards are midnight blue and text is cream. Cobalt, turquoise and burgundy accents mean the same in both themes; they are a little lighter in dark theme. Glass surfaces (the bottom capsule, the reader dock, the player) let the content behind them show through slightly in both themes.
In night mode the reader also inverts page colours (dark background, light text).
