What you get - One-click dark mode on any page, with a keyboard shortcut to toggle instantly. - Sunset auto-switch that turns dark mode on at dusk and off at sunrise, based on your local time. - True-black OLED presets that save battery on OLED laptops and phones by using pure black backgrounds. - Colour-blind-safe palettes so links, buttons and highlights stay distinct for everyone. - Per-site schedules and a whitelist, so sites you prefer in light mode always open that way. - Fine controls for brightness, contrast and sepia warmth to match your room. How it works Turn Zovo Night on and it applies immediately to the current tab. Use the popup to pick a preset, adjust brightness, or add the current site to your always-light list.
