Stellar blue-gray for crisp, midtone grid headers
About Stellar
Stellar reads like a midweight blue that's been softened by daylight, not dimmed into dusk. Compared to Night Market and Mississippi River, it's cleaner and more saturated, with a steadier blue tone instead of that muted evening teal or cooler slate current.
I reach for it when you want primary UI structure without going as dark as Midnight Shadow. It holds attention in dashboards and finance apps for card headers, status labels, and chart bands where you need clarity, not heaviness. In healthcare UI, it works for section bars, form step indicators, and table selection states when you want something serious that still feels fresh.
One quirk: Stellar sits a little cooler than a true "sky" blue, so next to warm off-whites it can look crisp and slightly withdrawn rather than friendly. Pair it with softer, neutral whites and restrained cool grays so it doesn't feel lonely.
