Prussian Blue (#013856) presents considerable accessibility challenges, primarily due to its low luminance. Its dark nature results in insufficient contrast against lighter backgrounds commonly used in web design. This can cause readability issues for users with visual impairments, including those with low vision or color blindness. To ensure inclusivity, it is crucial to pair Prussian Blue with significantly lighter colors. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as specified by WCAG guidelines. Using tools to evaluate color contrast is essential during design. Avoid using this color for essential information, like text or interactive elements, if sufficient contrast cannot be achieved. Consider providing alternative high-contrast themes for users who require them. This color might cause problems for people with impaired vision. Always check if contrast is sufficient.
