The hex color #191087, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, it fails to meet WCAG (Web Content Accessibility Guidelines) AA standards for normal text (4.5:1 contrast ratio). This means individuals with moderate visual impairments may struggle to read content displayed in this color. To improve accessibility, consider using #191087 for larger text elements (18pt or 14pt bold) or graphic elements, where a contrast ratio of 3:1 is acceptable. Pairing it with a much lighter color, such as a pale yellow or off-white, as a background can significantly enhance readability. Avoid using this color for critical information or interactive elements without careful consideration of contrast. Tools like WebAIM's contrast checker can help ensure compliance with accessibility guidelines and provide a better user experience for everyone.
