The hex color #170E8D, also known as Ultramarine, presents some accessibility challenges, especially regarding text contrast. When using this color for backgrounds, it's crucial to select text colors that provide sufficient contrast to ensure readability. White (#FFFFFF) or very light shades of yellow or gray are generally good choices. Tools like the WebAIM contrast checker can be invaluable in verifying that the contrast ratio meets WCAG (Web Content Accessibility Guidelines) standards, aiming for a minimum ratio of 4.5:1 for normal text and 3:1 for large text. It's also important to consider users with color vision deficiencies. Avoid pairing #170E8D with colors that might be difficult for them to distinguish, such as certain shades of blue or purple. Incorporating visual cues besides color, such as underlines or icons, can further improve accessibility. For interactive elements, ensure there's a clear visual indication of focus, such as a contrasting border or background change on hover or selection. Careful attention to these aspects will help create a more inclusive and user-friendly experience.
