Dark mode is not a trend anymore — it is a design decision. The best dark websites feel considered from the ground up, with high contrast, cinematic depth, and type that earns its space on a near-black canvas. And paired with gradients, the effect is even more powerful. Subtle color bleeds, glowing accents, layered depth — it is the aesthetic that SaaS products, AI startups, creative studios, and premium brands have been reaching for because it converts attention into credibility.
