The hex color #0A2B4E, also known as Blue Whale, presents some accessibility challenges, especially in text applications. Its low luminance makes it difficult to achieve sufficient contrast against lighter backgrounds like white or light gray. According to WCAG guidelines, sufficient contrast is essential for readability, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #0A2B4E for text on a white background might not meet these criteria, potentially causing discomfort or hindering comprehension. To improve accessibility, consider pairing it with much lighter colors or using it for larger elements where the contrast requirement is less stringent. Alternatively, you could lighten the color itself to increase its contrast ratio. When using this color for interactive elements like buttons or links, ensure that hover and focus states provide a clear visual distinction for users relying on keyboard navigation or screen readers. Always test color combinations with accessibility tools to verify compliance.
