About this palette

This 4-color pastel palette runs from Crushed Ice (#BEFFF7) as its lightest tone to Guilliman Blue (#6499E9) as its darkest. It blends Guilliman Blue, Columbia Blue, Waterspout and Crushed Ice into a single set you can drop straight into a UI. None of the 6 in-palette color pairings clear the WCAG AA contrast threshold (4.5:1), so pair these colors with black or white for body text.

Gentle, low-saturation tones — ideal for wedding sites, baby brands, soft hero sections, and editorial layouts that lead with whitespace.
