General Information about Prussian Blue

Prussian Blue, represented by the hex code #002E57, is a deep, rich shade of blue with a hint of green. It's named after the dye first produced in Prussia. Chemically, it's a complex iron cyanide compound. Historically, it was one of the first modern synthetic pigments, and it has been widely used in paints, inks, and dyes due to its strong tinting power and relative lightfastness. In color psychology, Prussian Blue is often associated with intelligence, stability, and authority. It can evoke feelings of trust, security, and sophistication. Because of these characteristics, it is often chosen by brands that want to appear professional, trustworthy, and reliable. The color is often used in formal settings.

The hex color #002e57, a deep Prussian Blue, presents specific accessibility considerations for web development. Its dark nature means it requires careful contrast evaluation, especially regarding text. 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 (14pt bold or 18pt regular). Using #002e57 for text on a white background will likely fail these guidelines. Therefore, it is crucial to pair it with significantly lighter colors to ensure readability for users, including those with visual impairments. When used for interactive elements like buttons, sufficient contrast must be maintained for states like hover, focus, and active to provide a clear visual indication of the element's status. Additionally, avoid relying solely on color to convey meaning, as colorblind users may not perceive the intended message. Consider using icons or text labels alongside the color to enhance usability.
