Prussian Blue
General Information about Prussian Blue
Prussian Blue, represented by the hexadecimal color code #02305B, is a deep, rich shade of blue with historical significance. Discovered accidentally in the early 18th century, it quickly became a widely used pigment due to its stability and affordability. Chemically, it's a complex iron cyanide compound. Prussian Blue has applications far beyond artistry; it's used in dyes, paints, and even in medicine to treat certain types of heavy metal poisoning. In digital contexts, its depth and sophistication can add a sense of elegance to designs, though considerations for accessibility are paramount due to its dark nature. The color resonates with feelings of trust, stability, and authority, which is why it is used by financial and governmental institutions. It is a color that can be associated with the sea and night.
The hex color #02305B, a deep Prussian Blue, presents accessibility challenges, especially when used as a background color for text. Due to its low luminance, it requires careful consideration to ensure sufficient contrast with foreground elements, typically 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 to meet AA compliance. Using a very light color such as white or a pale yellow is recommended for text on a #02305B background. Tools like contrast checkers can help assess compliance. It is not recommended to use it for important icons or clickable elements. This color may be better suited for decorative purposes or in larger graphical elements where readability is not critical. Careful selection of text and interactive elements is essential when using this color in user interfaces.
