The color #2103B1, a deep ultramarine, presents some accessibility challenges, especially in text-based contexts. When used as text against a white or light-colored background, the contrast ratio is likely insufficient, making it difficult for users with visual impairments to read comfortably. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. To improve accessibility, consider using #2103B1 as an accent color or in larger graphical elements rather than as the primary text color. When using it for text, pair it with a very light or white background or consider using a lighter shade of blue or a contrasting color such as yellow or orange for the background to enhance readability for all users, including those with low vision or color blindness. Proper contrast ensures that content is perceivable and usable by a wider audience.
