The color #0B0D8D, a deep ultramarine, presents some accessibility challenges, especially for users with visual impairments. Its low luminance value of approximately 1.3 cd/m² means it has very poor contrast against white backgrounds, failing WCAG standards for normal text (4.5:1) and large text (3:1). To improve accessibility, it's crucial to use this color with lighter text or interface elements to ensure sufficient contrast. Consider using a color contrast checker to verify compliance with accessibility guidelines. Additionally, avoid using this color as the sole indicator of important information; supplement it with text labels or icons to ensure inclusivity for all users, including those who are colorblind.
