#F3FFAF Hex Color

Muted greens and grays flatter #f3ffaf best, since its low saturation suits soft, natural palettes. Try olive or slate accents, and skip pure white neighbors, which make the yellow look washed out.

Yes. Black text on #f3ffaf reaches about 19.7:1 contrast, far above the 4.5:1 that WCAG AA requires for body text. Darker gray text also works, but avoid white or pale yellow type on it.
