The color #01129A, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value means that text rendered in this color requires very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using this color for text on a dark background would fail these guidelines, making content difficult or impossible to read for many users. To improve accessibility, consider using this color sparingly for decorative elements, or pair it with much lighter hues. Tools like contrast checkers can help evaluate the color pairings.
