Robust Gemini Royal

#3b62d2
Notes

Robust Gemini Royal (#3B62D2) 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 (225°, 63%, 53%) 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

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

Gemini
modifier

Latin gemini, twins-of-the-zodiac. As a color modifier, gemini implies a twins-and-air-sign-and-Mercury-ruled-mutable-air quality, the visual register of Castor-and-Pollux-Gemini-twins hand-twins-and-air-sign-and-Mercury-ruled-mutable-air Castor-and-Pollux-Gemini-twins-and-Argonaut-twins gemini-and-twins-and-air-sign surfaces under Castor-and-Pollux-Gemini-twins-and-Argonaut-twins late-spring-and-May-and-June mutable-air-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to castor and pollux 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.
