Dark interfaces can feel comfortable in low-light environments and suit products where people spend long periods reading or working. They can also give a brand a distinct visual character.
A mode with a purpose
But a dark palette is not automatically easier to use. Contrast, text weight, color meaning, and the surrounding environment all influence readability.
Design beyond inversion
Simply swapping light backgrounds for dark ones rarely produces a polished result. Revisit surfaces, borders, illustrations, and focus states as a system, and check how colors behave at different brightness levels.
Offer a clear way to choose a preferred appearance, and respect the device setting when it makes sense for the product.
Let your audience decide
Use research and accessibility testing to decide whether dark mode belongs in your experience. A well-supported choice is more useful than adding a theme only because it is fashionable.
