The hex color #181FBE, also known as Persian Blue, presents some accessibility challenges, particularly when used as text on a white or light-colored background. Its relatively low luminance (brightness) results in insufficient contrast, potentially making it difficult for users with visual impairments to read. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #181FBE for text, careful consideration must be given to the background color to ensure compliance with these guidelines. Lighter colors should generally be avoided, and darker shades should be preferred. Using online contrast checkers can help determine if the color combination meets accessibility standards. Furthermore, it is crucial to provide alternative ways to convey information, such as using icons or descriptive text, especially when the color alone might not be sufficient for all users. Employing CSS techniques, such as text shadows or borders, can also enhance the readability of text using this color.
