Uranus
Refreshing, pale cyan with cool undertones

Uranus is a pale, desaturated cyan that feels airy and cool. Because black text offers high contrast against this shade, the hex code #ace5ee serves as a practical choice for UI backgrounds. It works best when paired with dark charcoal to ground the lightness rather than white, which can wash it out. This tint maintains a refreshing, modern aesthetic in technology or children’s product designs.
