Dark Mode Done Right: A Practical Guide for Business Websites

Dark mode is easy to make look good in a single hero screenshot and surprisingly hard to make work across an entire site — forms, tables, charts, and long-form text all behave differently against a dark background than a light one.

Contrast rules that don't bend

Pure black backgrounds with pure white text create a harsh contrast that's genuinely tiring to read for long stretches — a slightly lifted near-black background with an off-white foreground is far easier on the eyes and still reads as premium. Every accent color also needs to be checked against the dark background specifically; a color that passes contrast on white frequently fails on near-black.

The other rule: don't reserve dark-mode thinking for the homepage. Error states, disabled buttons, and form validation messages are the elements that most often get forgotten and end up unreadable once real content moves through them.
