The color #180E8D, a deep ultramarine, presents considerable accessibility challenges, especially in text-based applications. Its low luminance value of 3.46 means it offers insufficient contrast against light backgrounds, making it difficult for individuals with visual impairments to read text rendered in this color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color fails to meet these criteria when paired with white or very light grays. To improve accessibility, it's crucial to use this color sparingly for text or to pair it with very light shades. When using this color for interactive elements, provide clear visual cues beyond color alone, such as borders, icons, or text labels, to ensure usability for all users. Careful consideration should be given to its use in charts and graphs to ensure information is conveyed effectively to all audiences.
