About this palette

This 4-color earthy palette runs from Red (#FF0000) as its lightest tone to Nero (#252525) as its darkest. It blends Nero, Red, All Systems Red and Spade Black 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.

Grounded, natural tones — suits sustainability/organic brands, coffee shops, outdoor gear, and warm editorial typography.
