However, its low luminance value means it requires careful consideration for accessibility, particularly in text and interactive elements. It can be perceived differently based on cultural backgrounds.

The hex color #181bce, also known as Persian Blue, presents several accessibility challenges for web developers. Its low luminance value of 0.03 means it provides insufficient contrast against a standard white background. This fails WCAG (Web Content Accessibility Guidelines) AA standards for normal text (4.5:1 contrast ratio) and large text (3:1 contrast ratio). Using #181bce for text or interactive elements on a white background would make it difficult for users with visual impairments to read or interact with the content. To improve accessibility, consider using a lighter background color or darkening the text color to achieve adequate contrast. Tools like contrast checkers can assist in evaluating and improving color contrast ratios to meet accessibility standards, ensuring a more inclusive user experience. Proper color contrast enhances readability and usability for all users, including those with low vision or color blindness.
