Resolute Goluboy

#1b6def
Notes

Resolute Goluboy (#1B6DEF) is a true azure with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (217°, 87%, 52%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Goluboy
noun

The Russian word for light blue — distinct from sinii (deep blue) in Russian color vocabulary, which (uniquely among major languages) names two separate basic blue categories. The color refers to a goluboy-painted Russian dacha shutter: a soft, slightly cool pale blue with the matte finish of weathered linseed-oil paint.
