The color #1E49C8, also known as Cerulean Blue, presents certain accessibility considerations for web developers. Its relatively low lightness value means it may not provide sufficient contrast against a white or very light background, potentially causing readability issues for users with visual impairments. When using this color for text, it's crucial to ensure a high contrast ratio, ideally meeting WCAG (Web Content Accessibility Guidelines) standards of at least 4.5:1 for normal text and 3:1 for large text. To improve accessibility, consider pairing #1E49C8 with lighter shades of yellow, white, or lighter blues for text or interactive elements. Additionally, providing alternative cues like icons or underlines for links is recommended, as relying solely on color might exclude users with color blindness. Testing the color combination with accessibility tools and users is always a good practice.
