The color #1C10A4, a deep ultramarine, presents several accessibility considerations for web developers. Its relatively low luminance value means it requires careful pairing with text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #1C10A4 as a background, light text colors like white or light yellow are preferable to meet these contrast requirements. Tools like WebAIM's contrast checker can be valuable for verifying compliance. Additionally, avoid using color as the sole means of conveying important information; supplement it with text or other visual cues to accommodate users with color vision deficiencies. Consideration should also be given to users with cognitive disabilities, for whom high contrast and clear visual hierarchy are essential for a positive user experience. Using this color sparingly and thoughtfully will significantly improve accessibility.
