Mariner#286ACD, a cool vivid blue

At a glanceMariner is #286ACD, oklch(53.8% 0.167 258.8), a cool vivid blue. Partner it with a warm bold scarlet #CA4D3C as an accent, a cool light turquoise #62BED8 for harmony, and a cool muted blue #707885 as a neutral. Reach for it as a text color on light backgrounds, or a screen-first brand or accent color, and it holds AA contrast against white. It shifts further on press than a run can hold, though, so Rhapsody would keep it off print-led brand work.
