‘Dark mode’ is appearing across device operating systems and websites alike. It may be a passing thing, or it may be something we’ll soon take for granted permanently, but either way, it exists now, and we need to consider its implications for the way our web properties display. While it’s unlikely that most of our sites will offer users a choice of light or dark mode, some third-party sites (like LinkedIn pages, where it’s being rolled out) may well do so. There can be problems with transparent images and text over images, and I’d thoroughly recommend an audit of your company’s managed and third-party (e.g. social media) sites, as well as emails, to ensure they look fine in ‘dark mode’, if available.
