Summit

On a light UI, Summit looks like sea-blue that's been sunlit just enough to soften the edges. It sits between the steadiness of Cool and the softer wash of Misty Cold Sea, but it doesn't blur into fog. Compared to Cuttlefish, it's a touch lighter and less dense, so it feels more breathable than "blue with weight."

What I like is the undertone: it stays clearly blue-leaning, yet the extra luminance keeps it from reading flat. I use Summit for dashboards and admin panels in health-tech and fintech, especially when you want section backgrounds, table header bands, and form field surfaces to feel crisp without getting clinical. It's also a solid choice for card headers and chart containers where other blues might feel either too muted or too busy. More airy than Cuttlefish, it still has enough saturation to hold as a deliberate layer.

Pair it with deep slate text and restrained accents. If you throw in highly green teal neighbors, Summit can start to look like it's drifting.
