The color #0537D1, also known as Persian Blue, presents significant accessibility challenges. Its very low lightness value (resulting in a dark appearance) means that it requires extremely light text (white or near-white) to achieve sufficient contrast for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Using #0537D1 as a background color necessitates careful selection of foreground colors to meet these guidelines. Tools like contrast checkers are essential to verify compliance with WCAG standards. It is generally not advisable to use it for text itself, especially in long passages. Consider alternatives that offer better inherent contrast or using this color sparingly for purely decorative elements. Ensure that any interactive elements using this color have clear focus states and provide alternative cues beyond color alone.
