The color #1A159F, a deep ultramarine, presents some accessibility challenges, particularly when used as text on a white or light background. Its low lightness value (approximately 12%) means it has insufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (AA conformance). To ensure readability for users with visual impairments, larger text sizes or higher font weights are necessary. When using this color for interactive elements like buttons or links, consider adding a lighter background or a white/very light text color to provide sufficient contrast. Another option would be to use a text shadow or a border to make the text stand out. Also check how it is displayed on different devices and screens. Careful consideration should be given to those with color blindness, as reliance on color alone to convey information can be problematic. Avoid using this color as the sole indicator of a specific state (e.g., active, error).
