The color #1C0197, a deep ultramarine, presents significant accessibility challenges, especially concerning color contrast. When used as a background, it requires very light text colors to ensure readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color is not suitable for interactive elements like buttons or links without careful consideration of the foreground color. Users with visual impairments may struggle to distinguish elements if the contrast is insufficient. Therefore, pairing #1C0197 with colors like white (#FFFFFF) or very light shades of yellow or gray is crucial. Avoid using it with darker colors or mid-tones, as this will likely result in poor readability and an inaccessible user experience. Testing with accessibility tools is recommended to validate color choices.
