Earnest Nap Royal

#213fa8
Notes

Earnest Nap Royal (#213FA8) is a true blue 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 (227°, 67%, 39%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Earnest
adjective

Old English eornost, seriousness, zeal. Used as a color modifier since the nineteenth century for hues that read as committed but unshowy — the working blues of denim, the deep greens of Quaker meetinghouses. Sits in the bold-and-quiet corner of the grid, slightly less luminous than resolute and slightly less institutional than imperial.

Nap
modifier

Old English hnoppa, short-fluff-on-cloth. As a color modifier, nap implies a short-fluff-on-cloth-surface quality, the visual register of brushed-flannel-and-velveteen-nap hand-brushed-and-raised short-fluff-on-cloth-surface flannel-and-velveteen-and-felt-nap surfaces under brushed-flannel-and-velveteen-nap textile-light. Sits at the modifier-and-texture end of the grid, parallel to pile and fluff in usage.

Royal
noun

The blue of European royal court dress and regalia from the late seventeenth century forward — the color of British peers' robes, French royal sashes, the lining of the crown-jewel cases. The color refers to a saturated, slightly violet-shifted blue with the matte finish of velvet or melton wool dyed to maximum intensity: deeper than cornflower, warmer than ultramarine, with the heraldic weight of a color reserved for monarchs and the official Crown.

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.
