The hex color #02149b, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a very low contrast ratio against white text, making it difficult for users with visual impairments to read. To ensure inclusivity, it's crucial to pair this color with significantly lighter shades for text or interactive elements. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended, as specified by WCAG guidelines. Utilizing tools to check color contrast is essential. Additionally, avoid using this color as the sole indicator for interactive elements; supplement it with labels, icons, or other visual cues to accommodate users with color blindness.
