Fresh Berth Lagoon
Fresh Berth Lagoon (#65D3CF) 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 (178°, 56%, 61%) 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
Old English fersc, unsalted / not stale — sharing root with German frisch. As a color modifier, fresh implies a clear-and-newly-applied quality where the hue carries the just-emerged visual register. Sits at the crisp-and-clean end of the grid, parallel to crisp and new in usage.
Middle Low German bert, bunk / sleeping-shelf. As a color modifier, berth implies a small-confined-shipboard quality, the visual register of Royal-Navy-period small ship-cabin-and-sailor's-bunk hand-built confined-and-functional sleeping-quarter surfaces under Royal-Navy-period below-decks oil-lantern shipboard-light. Sits at the modifier-and-place end of the grid, parallel to cabin and quay in usage.
A shallow body of saltwater partially or fully enclosed by a barrier — coral atoll lagoons in the Pacific, Venice's Laguna Veneta, the Florida Keys' backcountry. The color refers to the average reflectance of a calm tropical lagoon at midday: a saturated, slightly muted blue-green with the optical clarity of shallow water over white sand. Brighter than reef, cooler than aquamarine, with the postcard weight of a Pacific atoll seen from above.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
