General Information about Prussian Blue

Prussian Blue, represented by the hexadecimal color code #073457, is a deep, rich shade of blue with a hint of green undertone. It's named after the dye originally used to color Prussian military uniforms. This color is associated with qualities such as stability, trustworthiness, and intelligence. In color psychology, blue is often linked to calmness, security, and authority. Prussian Blue is a popular choice in various design applications due to its elegant and sophisticated appearance. It is created by mixing iron salts with cyanide, resulting in a pigment that is both stable and intensely colored. The pigment was first synthesized in the early 18th century and quickly gained popularity among artists and dyers.

The hex color #073457, a deep Prussian Blue, presents some accessibility challenges, primarily due to its low luminance. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to comply with WCAG AA standards. Using a color contrast checker is crucial to verify compliance. For users with visual impairments, including those with low vision or color blindness, insufficient contrast can render text illegible. Therefore, designers and developers must carefully select foreground colors that provide adequate contrast. Consider using tools that simulate color blindness to ensure content is accessible to everyone. Avoid using this color for small text or crucial interface elements without ensuring sufficient contrast. Also, consider providing alternative color themes to allow users to customize their viewing experience.
