The color #100D8B, also known as Ultramarine, presents some accessibility challenges due to its dark hue. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. If used for text itself, ensure the background is a very light color. Tools like contrast checkers can assist in verifying compliance. Consider users with visual impairments or color blindness when designing. Avoid relying solely on this color to convey important information; use supplementary cues like text labels or icons. Thorough testing with different user groups is advisable to validate accessibility.
