Translucent Inlet

#42bac5
Notes

Translucent Inlet (#42BAC5) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (185°, 53%, 52%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Translucent
adjective

Latin trans-lūcēre, to shine through — present-participle of translucere. As a color modifier, translucent implies a clear-and-light-passing quality where the hue allows partial light-transmission through its visual surface. Sits at the crisp-and-clear end of the grid, parallel to pellucid and vitreous in usage.

Inlet
noun

A narrow body of water leading inland from a sea or lake — particularly the saltwater inlets of the Pacific Northwest and Norway. Inlet color refers to a Pacific Northwest fjord inlet at midday: a saturated, slightly cool deep blue with the optical depth of cold-water tidal inlet.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
