The color #151487, a deep ultramarine, presents accessibility challenges. Its low luminance results in poor contrast against light backgrounds, potentially making text illegible for users with visual impairments. To improve accessibility, employ a high contrast ratio by pairing it with very light colors such as white or light yellows. Ensure that text using this color meets WCAG standards for contrast. Avoid using it for critical interactive elements without sufficient contrast. Providing alternative high-contrast themes can further enhance usability for all users, especially those with low vision or color blindness. Additionally, consider providing visual cues besides color to convey information to users with color vision deficiencies. The level AAA compliance asks for a contrast ration of 7:1 for normal text and 4.5:1 for large text.
