The color #1E03B1, a deep ultramarine, presents some accessibility challenges, primarily due to its low luminance. When used as a background color, it requires light-colored text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG 2.1 AA standards. Tools like contrast checkers can help verify compliance. This color may not be suitable for conveying critical information or interactive elements without careful consideration of text and background pairings. Users with visual impairments may struggle to differentiate elements using this color against dark backgrounds. Therefore, thoughtful design and testing with accessibility in mind are essential for inclusive design.
