The color #1B0E8D, a deep shade of ultramarine, presents accessibility challenges due to its low luminance. When used as a background, sufficient contrast with text is crucial to ensure readability for users with visual impairments. A light-colored text, such as white or a very pale yellow, is recommended. Tools like contrast checkers can help verify compliance with WCAG guidelines. For interactive elements like buttons, consider using a lighter tint of the ultramarine or a contrasting color for focus states to provide clear visual cues. Avoid pairing this color with similar dark shades as it can lead to a lack of differentiation and reduce usability. Providing alternative text for images and icons is essential for users who rely on screen readers. It is also important to test the color scheme with users who have different types of color blindness to ensure that the information is conveyed effectively.
