The hex color #210BBF, a deep, dark blue, presents some accessibility challenges, especially when used as a background color. Its low luminance value means that text layered on top of it needs to be a very light color (white or a pale yellow, for example) to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). When using #210BBF, designers must meticulously check contrast ratios to meet these standards. Using color contrast tools available online is essential. Avoid pairing it with other dark colors as this will make the text unreadable for many users, including those with visual impairments. Also, provide alternative visual cues beyond color alone to convey information, ensuring usability for colorblind users.
