The hex color #1B3DBB, also known as Persian Blue, presents some accessibility challenges, especially when used as a text color on a white or light background. Its relatively low luminance can make it difficult for users with visual impairments to read comfortably. According to WCAG guidelines, it's crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. When using #1B3DBB for text, consider pairing it with a very light color like #FFFFFF or other lighter shades to meet these contrast requirements. If used for interactive elements such as buttons, ensure sufficient visual cues beyond just color to indicate state changes, like adding an underline on hover for links, or using icons combined with text to convey meaning. This ensures a better user experience for everyone, including those with color vision deficiencies.
