Heartening Inlet
Heartening Inlet (#48D0F6) is a true cyan with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (193°, 91%, 62%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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 heorte (heart) — present-participle of hearten. As a color modifier, heartening implies a clear-and-uplifting-and-encouraging quality where the hue carries the visual register of cheerful-encouraging color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to welcoming and cheerful in usage.
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.
