The hex color #09138f, also known as Ultramarine, presents significant accessibility challenges, particularly regarding contrast. When used as text against a white background, it fails to meet WCAG (Web Content Accessibility Guidelines) AA standards for contrast ratio. This means that users with visual impairments, including those with low vision or color blindness, may find it difficult to read. To improve accessibility, consider using a lighter background color or a significantly lighter text color to increase contrast. Alternatively, for decorative purposes, ensure crucial information is not solely conveyed through color. Providing text equivalents and adhering to established accessibility guidelines will significantly enhance the user experience for everyone.
