The color #12098F, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) requirements for contrast ratio, making it difficult for users with visual impairments to read. Similarly, when used as a background color, text placed on top might need to be carefully chosen to ensure sufficient contrast. To improve accessibility, consider using lighter shades of yellow, orange, or green for text on this background, or, alternatively, use a lighter tint of Ultramarine as the background to increase the contrast against black or dark gray text. Tools like contrast checkers can help determine if the color combinations meet the necessary contrast ratios for different accessibility standards, ensuring that your designs are usable by a wider audience.
