The hex color #023355, also known as Prussian Blue, presents specific accessibility considerations for web design. Its dark hue offers inherent challenges in contrast. When used as a background color, it necessitates very light text to ensure readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Tools like contrast checkers can accurately measure this. Conversely, if used as text, a very light background is essential. Avoid pairing it with mid-tone colors, as the resulting lack of contrast can cause visual strain, especially for users with visual impairments. Thoughtful application of this color with accessibility in mind will ensure a more inclusive and user-friendly experience.
