The color #110593, a deep ultramarine, presents significant accessibility challenges, especially regarding contrast. When used as a background color, text needs to be very light (ideally white or a very pale yellow) to ensure readability. A contrast ratio of at least 4.5:1 is recommended for body text, and 3:1 for larger text elements. Using a color contrast checker is essential. Also, consider users with visual impairments or color blindness. Avoid using this color as the sole indicator of important information; supplement it with text labels or icons. Furthermore, interactive elements like buttons or links should have distinct visual cues beyond just color to ensure they are easily identifiable and usable for everyone. Sufficient spacing between elements helps to improve accessibility when dealing with low contrast colors.
