The color has historical significance, often associated with military uniforms and formal attire. In color psychology, Prussian Blue is linked to intelligence, authority, and conservatism. It is a versatile color that can be used in various contexts, from graphic design to fashion.

Prussian Blue is also known for its excellent lightfastness, meaning it resists fading over time.

The hex color #02345b, also known as Prussian Blue, presents significant accessibility challenges, primarily due to its low luminance. Its contrast ratio against a white background is very low, making it difficult for individuals with visual impairments, including those with low vision or color blindness, to discern text or graphical elements rendered in this color. To improve accessibility, it's crucial to pair Prussian Blue with significantly lighter colors that provide a high contrast ratio, ideally exceeding the WCAG (Web Content Accessibility Guidelines) recommended ratios of 4.5:1 for normal text and 3:1 for large text. Using tools to check color contrast is essential. Avoid using this color for critical information or interactive elements without careful consideration of the foreground color. Consider providing alternative color schemes to enhance usability for all users. Adding text shadows or borders can also help improve readability in certain contexts. When used as a background, ensure that all foreground elements have sufficient contrast.
