The hex color #2158C5, also known as Cerulean Blue, presents some accessibility considerations for web design. Its luminance value may not provide sufficient contrast against certain background colors, particularly white or very light shades. This can make text or interface elements difficult to read for users with visual impairments. To ensure accessibility, it's crucial to evaluate the color contrast ratio using online tools. Aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) as defined by WCAG guidelines. Pairing #2158C5 with lighter, contrasting colors like yellows or light greens can improve readability. Additionally, consider providing alternative color schemes to cater to users with specific visual needs or preferences. Remember that proper color contrast is not just about aesthetics; it's a fundamental aspect of inclusive design that ensures your content is accessible to everyone.
