Yes. Black text on Apatite Blue reaches roughly 4.6:1 contrast, which clears the WCAG AA requirement of 4.5:1 for small body text. White text falls short, so keep light type oversized if you use it.

Warm accents like terracotta and soft coral bring out its green side, while cream keeps the palette light. Cool grays tend to flatten it, so warm neutrals are the safer companion.
