Spick Sencha

#40cbb2
Notes

Spick Sencha (#40CBB2) is a true teal 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 (169°, 57%, 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

Spick
adjective

Old Norse spik-spakr, spike-new — sharing root with spic-and-span. As a color modifier, spick implies a clear-and-newly-cleaned quality where the hue carries the just-polished visual register of fresh-painted-and-fresh-cleaned surfaces. Sits at the crisp-and-clean end of the grid, parallel to spotless and pristine in usage.

Sencha
noun

The Japanese steamed-leaf green tea — the most-consumed Japanese tea, distinct from matcha (powdered) and gyokuro (shaded-grown). The color refers to fresh-brewed sencha in a porcelain cup: a saturated, slightly cool deep blue-green with the optical clarity of steamed-leaf green-tea liquor.

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.
