Appearance

Choose light or dark, an accent colour and how much it tints Luma. Luma also follows Windows’ contrast themes.

Everything on this page is in Settings › Appearance (Ctrl+,). The small window at the top of the page shows each change as you make it.

Theme

Theme is System by default: Luma is light or dark when Windows is. Choose Light or Dark to keep one of them.

Accent colour

Accent color colours buttons, highlights and your first workspace. Choose one of the six preset colours, Luma violet (the default), Indigo, Ocean, Sage, Amber and Graphite, or:

  • Windows accent: the accent colour set in Windows, and it changes when you change it there.
  • Custom color: opens a colour picker for any colour. Luma adjusts it so that it stays readable in light and in dark mode.

Colour the whole browser

This slider sets how much the accent colour tints backgrounds, the sidebar, toolbars, menus and Luma’s own pages, from 0 to 100 % (8 % by default, so the interface stays almost neutral; towards 100 % the whole window clearly takes the colour). At 0 it shows Off: the accent only colours buttons, highlights and the mark on the selected tab.

Transparency

Reduce transparency (off by default) uses solid surfaces instead of translucent materials.

Contrast themes

If you turn on a contrast theme in Windows (Settings › Accessibility › Contrast themes), Luma follows it: the window, its menus and panels, and Luma’s own pages take the theme’s colours.

Efficiency mode

Efficiency mode is in Settings › Performance. It uses less memory, CPU and battery: background tabs sleep after 10 minutes, and the interface skips animations and blur effects. It is off by default; it helps on older PCs and on battery.
