Dark mode isn't just inverting colors. Doing it well takes care with contrast, elevation, and the small details most teams skip.
Dark mode is one of the most requested features and one of the most commonly botched. Flipping black and white is the easy part. Making it feel intentional — readable, calm, and consistent — is where the real work lives.
Pure black is rarely the answer
True black with pure white text is harsh and makes the screen feel like it's vibrating. A deep, slightly-warm charcoal with a soft off-white reads far better and reduces eye strain in the low-light situations where dark mode actually gets used.
- Use layered surfaces, not borders, to show elevation — lighter means closer.
- Desaturate accent colors slightly so they don't glow against the dark.
- Re-check every contrast ratio; light-mode values don't carry over.
- Test real content — long text, images, and empty states, not just the happy demo.
Dark mode isn't a filter you apply at the end. It's a second design that has to be just as considered as the first.
Get the fundamentals right and dark mode stops being a checkbox and starts being a genuinely better experience — the one a lot of your users will quietly prefer.
