When used as text on a white background, the contrast ratio might not meet WCAG (Web Content Accessibility Guidelines) standards for level AA compliance, especially for users with visual impairments. To ensure accessibility, it is recommended to pair this color with lighter shades of yellow, white, or other very light colors for text. Alternatively, consider using it for larger text sizes where the contrast requirements are less stringent. When used as a background, pair it with white or very light text. For interactive elements, ensure sufficient visual cues beyond color alone are present to communicate state and function. Tools such as contrast checkers can help assess compliance with accessibility standards and identify suitable color pairings.
