#91E391 Hex Color

Deep charcoal or near-black tones provide the best balance for this high-chroma green because they ground its synthetic brightness. Using dark text or borders over #91e391 ensures the interface remains readable while maintaining a modern, high-contrast aesthetic for users.

Avoid using #91e391 as a primary background color because its extreme saturation can overwhelm the viewer and cause eye strain. Instead, apply it sparingly as a punchy accent for buttons, status indicators, or highlights where high visibility is required for user interaction.
