What makes it Studio Cerulean.
Three measurable properties separate this palette from its neighbours.
Single hue family
Hue 200° – 215°
All five tones live in the cyan-blue band. The palette is monochromatic in hue but spans the entire luminance scale.
High saturation in the middle
Saturation 35% – 78%
Cerulean and Studio Blue carry the saturation; the deepest and lightest tones are restrained so the mid-tones can sing.
Strong value contrast
Lightness 17% – 97%
Indigo Deep to Ice Paper is a near-full value ladder — confident enough for editorial and dense data, calm enough for product surfaces.
Where it works.
Three registers where the palette earns its place — not every brief wants this palette, and that's the point.
Editorial & motion
Long-form magazine layouts, science writing, motion identity. The palette reads as authoritative without going corporate.
Data interfaces
Indigo Deep for chart frames, Cerulean for primary series, Sky Wash for secondary. The contrast lets dense numbers stay legible.
Civic & cultural brands
Museums, public-sector portals, philharmonics. The palette has weight without grandstanding.
