Its relatively low lightness value means it may not provide sufficient contrast when used with light-colored text or interface elements. Web developers should ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) as per WCAG guidelines. Using a color contrast checker is essential to verify compliance. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light or white background. Avoid using it for critical interactive elements without proper contrast. Additionally, provide alternative text descriptions for any visual elements using this color to aid users with visual impairments.
