Spick Echium

#64aac8
Notes

Spick Echium (#64AAC8) 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 (198°, 48%, 59%) 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 orange. 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.

Echium
noun

The genus Echium — Mediterranean and Macaronesian biennials with tall deep-blue flower spikes. E. vulgare (viper's bugloss) covers European chalk grasslands; E. wildpretii of Tenerife produces three-meter spires. The color refers to fresh E. vulgare in flower: a saturated, slightly cool deep blue-violet.

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.
