#2a5b6f is a dark cyan pulled toward gray, giving it a moody, low-key character instead of a bright tropical feel. Its dimness works well for dark mode backgrounds and large UI surfaces, and white body text clears AA on it with a 7.4:1 contrast ratio. Pair it with dusty coral or warm sand to offset the chill. As a dominant base it holds up; as a small accent it can read muddy.
