You might soon be able to rummage through the internet… but in dark mode. The Big G is testing a dark theme for Google Search on Chrome.

For now, the feature is solely available in Google’s experimental versions of the browser, Chrome Canary and Chrome Dev, as Google9ot5 has spotted. From the looks of it, though, the feature is still in early development — and it doesn’t always work as intended. It’s also limited to mobile only for the time being.
