The color #2108AC, also known as Ultramarine, presents some accessibility challenges, particularly in text-based applications. Its dark hue necessitates careful consideration of contrast ratios. When using Ultramarine as a background color, it's crucial to pair it with light-colored text (white or very light shades of yellow or gray) to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) AA standards. For AAA compliance, even higher contrast ratios are preferable. Avoid using Ultramarine for small text or interface elements without sufficient contrast, as this can cause eye strain and make it difficult for users with visual impairments to perceive the content. Tools like contrast checkers can help verify compliance with accessibility standards. Furthermore, consider providing alternative color schemes for users who might have specific visual preferences or requirements.
