The hex color #120aaa, a deep ultramarine, presents several accessibility considerations for web design. Its high saturation and relatively low lightness value mean that sufficient contrast with text is crucial for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #120aaa as a background, ensure that the foreground text is a light color like white or a very pale yellow to meet these contrast requirements. Also, avoid using this color alone to convey important information; supplement it with text labels or icons to ensure understanding for colorblind users. Carefully consider the overall color scheme and provide alternatives for users who may have difficulty perceiving the color difference. For interactive elements, ensure a distinct visual change on hover or focus to indicate interactivity.
