The hex color #151187, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its dark hue results in a low contrast ratio against light backgrounds, potentially making text or interactive elements difficult to read for users with visual impairments. To ensure inclusivity, it is crucial to use lighter text colors such as white or very light gray when placing text over this color. Alternatively, consider applying a color contrast checker to verify compliance with WCAG (Web Content Accessibility Guidelines) standards. Sufficient contrast enhances readability and usability for all users, including those with low vision or color blindness. When using #151187 for interactive elements, provide clear visual cues beyond color alone, such as distinct borders or text labels, to ensure users can easily identify and interact with them.
