Sky sits in the pastel band at #82cafc. The name carries a real history — sky has been describing this part of the spectrum for longer than the spectrum has been a word.
From the word sky
The blue of a clear sky at noon — produced by Rayleigh scattering, the preferential dispersion of shorter wavelengths through atmospheric molecules. Air itself is colorless; the color we see is sunlight scattered toward our eyes by every cubic kilometer above. The reference shade is mid-latitude noon under a high pressure system: a clean, slightly green-shifted blue with the luminous depth of light scattered across an entire hemisphere of air.
A saturated cool azure
Sits at OKLCH lightness 0.81, chroma 0.101, hue 240° — a saturated cool azure, the kind of color that carries a clear hue without shouting.
Light enough that small body text needs a near-black foreground; pure white on this background reads as a blur for anything under 18pt.
Pairings + neighbors
Triadic counterparts sit at #fc83c9 and #c9fc83 — three slices of the wheel 120° apart, the classic balanced trio. The pairings stay in the pastel register if all three keep their saturation; pull one toward neutral and the trio turns into a feature-with-supporting-cast.
The closest curated cousin in the library is Glacier at #93c5fd — a near-perceptual match (ΔE 7.1 in CIELAB). Worth the click if today's color almost works but you want to test a sibling.
