#E4F0EF Hex Color

Cloud leans cool from its faint cyan undertone, though a gray cast softens it. Next to pure white it reads slightly duller and greener, which keeps large background areas from feeling clinical.

Black text reads most clearly, with a contrast ratio of about 18.0:1 against #e4f0ef. That clears the WCAG AA threshold of 4.5:1, so small body text stays accessible on this shade.
