Dark Mode / Dark UI websites

Dark design stopped being a toggle and became a default for a whole class of products — developer tools, AI apps, anything that wants to feel modern and a little serious. Done well, a dark page concentrates attention: glowing accents, product screenshots, and gradients all pop against near-black in a way they never could on white, and the eye goes exactly where you point it. The craft is mostly in the greys. Pure black on pure white is harsh in reverse, so the strong dark pages layer near-blacks and dark greys to build hierarchy — surface, card, border — instead of leaning on heavy lines. Text drops to a soft off-white rather than full #fff to cut glare, and a single accent color does the work of every call to action. Contrast still has to clear accessibility floors; "looks moody" is not an excuse for grey-on-grey body copy nobody can read. The failure mode is using dark to hide weak structure. Low contrast and a smear of gradient can make an underbaked layout look intentional — until someone tries to actually read it. Dark rewards discipline and punishes mud.
