The hex color #0137E5, a deep shade of Persian Blue, presents several accessibility considerations for web developers. Its high level of saturation and relatively low luminance can pose challenges when used as text color against a white background. According to WCAG guidelines, sufficient contrast is crucial 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. When using #0137E5 for text, it's essential to choose a background color that provides adequate contrast. Lighter shades of gray or yellow might offer better readability than pure white. Alternatively, #0137E5 can be effectively used for decorative elements, backgrounds, or accents where precise readability is less critical. Ensuring that all interactive elements using this color have clear visual cues for focus and hover states is also vital for accessibility.
