The color #101688, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio might not meet WCAG (Web Content Accessibility Guidelines) standards, potentially making it difficult for users with visual impairments to read. To improve accessibility, consider pairing it with lighter hues or using it for larger text elements. Conversely, when used as a background, ensure the text placed on top is sufficiently bright. Tools such as contrast checkers can help determine if the color combinations meet accessibility criteria. Additionally, avoid using this color as the sole indicator for interactive elements such as links or buttons; always provide alternative visual cues like underlines or icons.
