The hex color #182a51, also known as Blue Zodiac, presents specific accessibility considerations for web design. With its dark hue, it is crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. When using #182a51 for text, pair it with very light colors like #ffffff (white) or shades of yellow to meet these contrast requirements. Avoid pairing it with mid-tone or darker colors, as this will likely result in insufficient contrast, making the text difficult to read for users with visual impairments. Testing with accessibility tools is highly recommended to validate the contrast ratio and ensure compliance with accessibility standards. Consideration should also be given to users with color vision deficiencies, ensuring that color is not the sole means of conveying important information.
