Why another dark mode
Gmail’s own Dark theme darkens the frame around your mail, but HTML emails such as newsletters, receipts and notifications still open on their sender’s white background. This extension darkens those too.
How it works
Gmail’s colours change without notice, so the extension doesn’t restyle them one by one. It inverts
the page’s colours and turns the hues back, which keeps links, labels and brand colours in their own
colour family, then turns pictures, videos and avatars back so they keep close to their real colours.
If Gmail’s own Dark theme is on, it leaves the page alone and marks the toolbar icon in that tab
with ! to say why.
What it does
- Darkens all of Gmail. The inbox, conversations, message bodies and the compose window.
- Keeps pictures close to real. Photos, avatars and emoji keep close to their own colours.
- Turns on and off with one click. Click the toolbar icon. Your choice is remembered.
- Stays out of everything else. It runs only on
mail.google.com.
Known limitations
- Pictures with a white background inside an email (logos, signatures) stay white.
- Pictures keep close to their real colours, but strong, saturated colours (a bright red, say) come out muted.
- A background picture with text over it stays inverted, so the text stays readable, unless the picture is sized to cover its box (a hero photo), in which case both keep their real colours.
- Gmail’s picture themes (a photo behind the inbox) may look wrong; the default theme works best.
- With Gmail’s own Dark theme on, the extension stays off, so message bodies keep their white
backgrounds there. The toolbar icon shows
!in that tab, and its tooltip says to switch Gmail to the Default theme (Settings → Themes) for a full dark mode. - Google may change Gmail at any time, which could break the theme until the extension is updated.

Free, with an optional tip
The extension is free and never unlocks anything. If it saves your eyes, you can leave a tip from the toolbar icon’s right-click menu, or on Buy Me a Coffee.
