The hex color #023455, also known as Prussian Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, text needs to be carefully selected 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 to meet AA standards. Given the darkness of Prussian Blue, lighter colors like white, yellow, or light gray are suitable choices for text. Tools like contrast checkers can precisely measure the contrast ratio. When using this color for interactive elements, ensure sufficient visual cues beyond color alone are present. Consider adding borders or using icons to help users perceive the element's state or function. It's also important to evaluate color blindness to make designs more inclusive.
