Ravenclaw
Also known as: Alucard’s Night , Abyssal Blue , Scoop of Dark Matter , Prussian Nights
Ravenclaw brings a calm and trustworthy feel to a palette. This deep blue suits trust-driven interfaces and corporate branding. Because it leans cool, balancing it with a black keeps a palette from feeling one-note. On white it reads clearly at 18.01:1 contrast, safe for body text under WCAG AA.
