The hex color #283A57, also known as Cello, presents some accessibility challenges. Its relatively low luminance value of 13 makes it difficult to achieve sufficient contrast against a white background, failing WCAG AA and AAA standards for normal text. For optimal readability, especially for users with visual impairments, it's crucial to pair #283A57 with lighter colors. Text using this color should be large or bold to improve contrast. Consider using a color contrast checker to ensure compliance with accessibility guidelines.
