Deep, clean cobalt-blue for primary accents
About Pure Blue
Pure Blue is the blue you notice when an old link tint finally gets replaced and everything stops drifting. It reads as blue first, full stop, with a calmer undertone than the more volatile ultrablues and a less physical weight than Brutally Blue. It feels clean and unarguable without turning electric or unsettled.
In production UIs, I use it for things that must look like they're meant to be blue: selection highlights, active tabs, and status callouts in dark mode. It holds up for dashboards and finance apps where you want clarity over drama, but it also works in gaming HUD layers that need link-like consistency without that slightly warm "strict" edge. Compared to Hyperlink Blue, it's not a burned-in web artifact, it's smoother and more deliberately balanced.
Pair it with cool grays or neutral whites, and keep warm accents restrained. Too much amber next to it can make the whole system feel oddly chilly, like the UI got set to a stricter mood than you intended.
