The hex color #0B3CBF, also known as Persian Blue, presents significant accessibility challenges. Its low luminance of 1.8 cd/m² means that text rendered in this color against a white background would fail WCAG (Web Content Accessibility Guidelines) contrast requirements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To improve accessibility, it is highly advised to pair Persian Blue with very light colors like white (#FFFFFF) or very bright yellows or oranges. Using darker shades or tints of blue as a background for white text is also not recommended. The use of Persian Blue should be carefully considered to ensure that content remains legible and usable for individuals with visual impairments, including those with low vision or color blindness. Adequate contrast enhances readability and overall user experience.
