The color #21616A, also known as Casal, presents moderate accessibility challenges. Its relatively low luminance contrast against white text may pose readability issues for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG AA guidelines. When using #21616A as a background, consider pairing it with lighter text colors like white or very light grays to ensure sufficient contrast. Tools like contrast checkers can help assess compliance. Additionally, avoid relying solely on color to convey important information, as users with color blindness may not perceive the intended message. Providing alternative visual cues, such as icons or text labels, can enhance overall accessibility.
