Today current purple
#1 Coastal Teal fresh · breezy
#3 Arctic Slate sophisticated · cool
Coastal Teal's spark accent is coral #fb7185 — a warm color. You deliberately skipped every warm direction (coral, tangerine, amber) in the explorer. So Coastal Teal is a cool frame with a warm pop; Arctic Slate is cool all the way through (sky-blue accent). If "get away from warmth" was the point, that accent matters.
Easy fix if you love the teal frame: keep Coastal Teal but swap its coral accent for a cool one (sky/cyan). That's a third option — a blend.
Arctic Slate is the safer match to your stated direction — cool top to bottom, reads "sophisticated/premium," and its slate-neutral base plays nicely against the content cards. Coastal Teal is more energetic and distinctive but the coral accent reintroduces the warmth you moved away from.
