My dark theme looked fine until I tested it on an old tablet | Dark Mode Design

I spent a week on a dark theme for a client's app, using pure black for the background and a bright blue for accents. It looked sharp on my new phone and my laptop. Then I pulled out an old tablet from 2018 to check it. The pure black background looked flat and muddy, and the bright blue text was vibrating against it, giving me a headache after five minutes. I realized I'd designed only for high-end OLED screens. The fix was simple but took me a full afternoon: I switched the background to a dark gray, something like #121212, and toned down the accent color's saturation by about 20%. Suddenly, it looked good on every device I tested, even that old tablet. It's a basic thing, but it's easy to forget when you're working on modern gear. Has anyone else had a theme fall apart on older hardware?

My 2016 iPad is my secret testing weapon.

What's the oldest device you test on now?

It's like when you buy a fancy new TV and everything looks amazing, then you go to a friend's older set and the picture is just off. You get used to the best version of things (like those OLED screens) and forget most of the world isn't there yet. I see it with audio too, where a mix sounds perfect on good headphones but turns to mud on a cheap Bluetooth speaker.
