When Did We Transition from Dark Mode to Light Mode on Computers?

I can’t pin down an exact date, but the move to light mode definitely happened before the early 2000s. For instance, Windows 95 had a light interface. My Amiga 500 back in the '90s even sported a bright GUI with customizable colors.

Yeah, GUIs started to become popular mostly for document processing, which worked well with white backgrounds. When you're dealing with low-level programming, it makes more sense to keep the pixels off than deal with trying to manage the ones you want to light up. Plus, old CRT screens had limited lifespans, so keeping them less active helped.

The Macintosh officially introduced light mode as the default in 1984. It existed before, but that was the point when it became a prevalent choice for users.

Originally, screens used a dark mode for technical reasons—it was cheaper. The characters only needed to light up rather than illuminating the whole screen. Light mode was around in the late '60s, but it wasn't until GUIs became mainstream that light mode really took off, like with the Apple Mac.

The shift to light mode really picked up with the introduction of the Macintosh in the mid-'80s, and later Windows followed suit. The idea was to mimic the look of printed text on white paper, which people were already used to. Dark mode was simpler and less energy-intensive back then—it's easier to light up just a few pixels than keep the whole screen bright, after all.
