The color #1C0FA5, also known as Ultramarine, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it's crucial to pair it with text that is sufficiently light to ensure readability. White (#FFFFFF) or very light shades of gray are generally recommended. Conversely, using dark text on an Ultramarine background can make it difficult for users, particularly those with visual impairments, to discern the content clearly. To meet WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools are available online to calculate the contrast ratio between two colors, which can help designers make informed decisions and improve the overall user experience. Careful consideration of color combinations is essential to ensure that content is accessible and inclusive to all users, regardless of their visual abilities. Also consider adding alternative text for images.
