The hex color #223A50, also known as Nile Blue, presents some accessibility considerations for web development. Its relatively low lightness value means that it requires careful pairing with contrasting colors to ensure readability and usability, particularly for users with visual impairments. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast between foreground text and background colors is crucial. When using #223A50 as a background, it's essential to select a light-colored text, such as white or a very pale yellow, to meet the minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify that the color combinations meet these guidelines. Avoid using #223A50 for small text or important UI elements if adequate contrast cannot be achieved, as this can exclude users. Incorporating sufficient spacing and padding around text and interactive elements can also improve readability when this color is used.
