Neat Sininen
Neat Sininen (#37A2BE) is a true cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (192°, 55%, 48%) 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 French net, clean / pure — sharing root with Latin nitidus. As a color modifier, neat implies a clear-and-orderly quality where the hue carries the well-arranged visual register without clutter or excess. Sits at the crisp-and-orderly end of the grid, parallel to trim and tidy in usage.
The Finnish word for blue — used for the Suomenlippu (Finnish flag) and the saturated blue of Finnish lake water. Sininen covers the entire blue-cyan spectrum in Finnish color vocabulary. The color refers to a Finnish lake at midsummer: a saturated, slightly cool deep blue with the optical depth of clear glacial-lake water.
