When used as a background color, it's crucial to ensure sufficient contrast with the foreground text or elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Given its dark nature, using lighter colors like white, light gray, or yellow for text on a #004d80 background is advisable to meet these standards. Tools like contrast checkers can help verify compliance. Also, avoid using color as the sole means of conveying information; supplement it with text or icons to accommodate users with visual impairments. Providing alternative text for images and ensuring proper semantic HTML structure further enhances accessibility when using this color.
