The color #100A8F, also known as Ultramarine, presents accessibility challenges due to its dark hue. When used as a background color, it requires light-colored text to ensure sufficient contrast for readability, adhering to WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet AA standards. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Designers should use contrast checking tools to verify compliance. Additionally, avoid using this color as the sole indicator of interactive elements like links, as users with color vision deficiencies may not be able to distinguish them. Supplement color cues with text labels or icons. Careful consideration ensures that content remains accessible to all users, regardless of visual abilities.
