The hex color #1B3ACB, also known as Persian Blue, presents some accessibility challenges, especially when used for text. Its relatively low luminance can create insufficient contrast against light backgrounds, making it difficult for users with visual impairments to read. To ensure accessibility, it's essential to pair #1B3ACB with a sufficiently light background color, like white or a very pale yellow. Using contrast checking tools is highly recommended to verify that the color combination meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Furthermore, avoid using #1B3ACB as the sole indicator for important interactive elements; supplement it with other visual cues like underlines or icons to ensure inclusivity for all users.
