The hex color #0B1190, also known as Ultramarine, presents significant accessibility challenges due to its very dark hue. Its contrast ratio against white is quite low, which can make text and other elements difficult to read for individuals with visual impairments. To ensure accessibility, it is crucial to use this color sparingly, especially for text or interactive elements. When using #0B1190 as a background, pair it with very light colors such as white or light yellow for text to meet WCAG (Web Content Accessibility Guidelines) requirements for contrast. Avoid using it with mid-tone or dark colors, as this will likely fail accessibility standards. Thoughtful consideration of color contrast is essential to provide an inclusive experience for all users. Also consider providing alternative styling options to allow users to customize their viewing experience.
