The color #180D8E, a deep ultramarine, presents some accessibility challenges, especially when used for text. Its low luminance value (relatively dark) requires careful consideration of contrast ratios against background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text against its background to meet AA compliance. When using #180D8E for text, it's crucial to pair it with very light colors like whites (#FFFFFF) or light yellows (#FFFF00) to ensure readability for users with visual impairments. For graphical elements and user interface components, a contrast ratio of 3:1 is required. Avoid pairing it with mid-tone or dark colors, as this can make content difficult to perceive. Using contrast checking tools is highly recommended to verify compliance and ensure an inclusive user experience. Consider also providing alternative styling options to allow users to adjust colors based on their preferences.
