Deep sea water comes close. #0a3e56 is a muted navy with gray, almost ashy undertones, so it reads serious and steady rather than playful. Its low saturation and dark value make it a strong dominant base for dark UI, finance, or nautical branding. White text sits at about 11.4:1 contrast, well past AA. The depth comes from its muted lightness, not from mixing black into a brighter blue.
