The hex color #100398, a deep ultramarine, presents some accessibility challenges, particularly concerning color contrast. When using this color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). This deep blue will likely require very light text (white or near-white) to meet these standards. Tools like WebAIM's contrast checker can help verify compliance. Also, consider providing alternative visual cues beyond color to ensure usability for users with color vision deficiencies. Using text labels, icons, or patterns in addition to color can significantly improve accessibility. For interactive elements, ensure that focus states are clearly visible. Keyboard navigation should be smooth and the visual indication of focus should be distinct and contrasting.
