The hex color #1B43BB, also known as Persian Blue, presents some accessibility challenges, particularly in text applications. Its relatively low luminance value means that it requires careful consideration of contrast ratios when paired with other colors. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. When using #1B43BB as a background or foreground color, ensure that the accompanying text or elements have a high contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. White (#FFFFFF) or very light shades of gray are usually good choices for text against a #1B43BB background. Tools are available online to check contrast ratios and ensure compliance with accessibility standards. Employing techniques like color modifiers or text shadows can also improve readability. Proper use of ARIA attributes can further enhance accessibility for assistive technologies.
