The color #0137D5, a deep shade of Persian Blue, presents considerable accessibility challenges. Its low luminance value of 0.02 means it offers very poor contrast against white backgrounds, failing WCAG standards for normal text (AA) and large text (AA). Even against black backgrounds, the contrast ratio is insufficient for optimal readability. To improve accessibility, consider using this color sparingly for decorative elements or pairing it with much lighter colors, such as shades of white, cream, or very light blues. Ensure the contrast ratio meets at least 4.5:1 for normal text and 3:1 for large text and graphical elements as per WCAG guidelines. Providing alternative text descriptions for images using this color is also essential for users with visual impairments. Always prioritize user experience by rigorously testing color combinations with accessibility evaluation tools.
