#DEFF21 Hex Color

This shade requires grounding colors to prevent visual fatigue. Use deep charcoal or dark navy for text and structural elements to balance its extreme brightness, or pair it with muted neutrals to keep the design professional.

Because #deff21 is extremely bright, it fails WCAG contrast requirements when used with white text. It must be paired with black or near-black text to maintain readability and ensure accessibility for users with visual impairments.
