This month Apple released dark mode on iOS 13 (see here) and with it comes a whole new trend for design. Well I say new, but before the iOS update, Twitter had dark mode on desktop since at least 2017 (see here) with YouTube following suit in 2018 (see here). While it’s still a newer trend compared to something like flat design (see here)—which as I recall became popular in the early to mid-2010s—it’s still slowly been growing in popularity.
So what is dark mode and what’s so great about it?
Dark; not black
Dark mode themes are more than just inverting your light colours and calling it a day. There are subtleties in a dark theme just as there are in a light theme—using colour to make elements like URLs stand out; not using pure black but instead an almost-black/dark colour; knowing which shade of grey to pick with a high enough contrast. According to one article (see here) this is something missing from some apps that have released a dark mode where they confuse it for a greyscale theme with no colour whatsoever (as in their Instagram example) or they don’t take colour contrast into account for active & hovered states. While this technically still a dark theme, it isn’t necessarily good design. Knowing how to make a dark theme work well is imperative for your users’ experience.
Saving your eyes & screen
Sometimes I enjoy a little night-time reading before bed but my screen feels too bright even on the lowest setting. Dark mode’s especially helpful in combatting this by reducing eye strain in a low-light area, like a dark bedroom. As a bonus, it’s also great for your screens to prevent screen burn. Screen burns (see here) are a permanent discolouration in your screen that cause a ghosting effect of what was once on your screen (#spooky). With a dark theme helping keep the overall brightness of your screen low, screen burns are less likely to occur.
Ok, let’s go dark!
Before you go turning down the proverbial lights on your website/app, it’s important to consider if this will be the right move for your company or product. A darker colour palette has certain connotations that go with it. If your company has branded itself as inviting and warm, then a dark theme may not be for you. If your product is for burly moustachioed men who own Harley Davidsons, this may be the right call to make. Colour plays an important factor in this decision, so consider your entire colour palette and your primary brand colours before you go dark.
