The color #223B47, also known as Nile Blue, presents some accessibility challenges. Its relatively low luminance value of 0.11 doesn't provide sufficient contrast against a white background, failing WCAG's AA and AAA standards for normal text. This means individuals with visual impairments might struggle to read text displayed in this color on a white background. To improve accessibility, consider using #223B47 for larger text elements or pairing it with lighter backgrounds. Calculating the contrast ratio using online tools is essential to ensure compliance with accessibility guidelines. Aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against its background. Furthermore, avoid relying solely on color to convey important information; supplement it with text labels or icons for users who are colorblind.
