The hex color #1B3BCB, also known as Persian Blue, presents some accessibility challenges, especially in text applications. Its relatively low luminance value (approximately 0.1) means that it requires careful consideration of contrast ratios. When used as a text color, it's crucial to pair it with a light background to ensure sufficient contrast for readability, meeting 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. Using a color contrast checker tool can help verify compliance. Conversely, when used as a background color, pairing it with white or very light-colored text can enhance readability. Avoid pairing it with dark or similarly saturated colors, as this can cause eye strain and reduce accessibility for users with visual impairments.
