The color #1B3FBB, also known as Persian Blue, presents some accessibility challenges. Its relatively low luminance value of 0.11 makes it difficult to achieve sufficient contrast against lighter backgrounds like white (#FFFFFF). According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text to ensure readability for users with visual impairments. Using #1B3FBB as text color on a white background would likely fall short of these requirements. Web developers should carefully consider the background color choice or adjust the color to a brighter shade to improve contrast. Also, consider using color combinations that are distinguishable for individuals with color vision deficiencies. Tools like contrast checkers can help evaluate and improve color choices for optimal accessibility.
