The hex color #283C59, also known as Cello, presents some accessibility challenges, especially when used for text or interactive elements. Its relatively low luminance contrast against a white background means that users with visual impairments may struggle to distinguish content effectively. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #283C59 on a white background falls short of these recommendations. To improve accessibility, consider pairing it with lighter colors to achieve sufficient contrast or using it sparingly for decorative purposes where contrast is less critical. Always test color combinations with accessibility tools to ensure compliance with WCAG standards and meet the needs of all users.
