Hydro
Also known as: Flip , Wild River , Silken Peacock , Winter Storm
On screen, Hydro registers as cool and clear: a rich cyan at home in modern branding and tech interfaces. Because it leans cool, balancing it with a brown keeps a palette from feeling one-note. It's dark enough to use for text on white backgrounds (5.14:1, passes WCAG AA).
