Using this palette

Real glacial ice is denser and bluer the deeper it's compressed, which is the physical reason this ramp gets darker rather than just 'more blue' toward one end — #001F3F is closer to a crevasse shadow than a sky color. That gives it more weight than a typical light 'ice' palette and makes it usable for serious brand contexts (outdoor/expedition gear, climate/science content) rather than only decorative winter themes. #0074D9 on white clears AA; #7FDBFF and #DFF6FF are backgrounds and dividers only. Pairs oddly with warm accent colors — if you need a CTA that isn't blue, orange is the honest complementary choice, not red.
