General Information about Prussian Blue

Prussian Blue, represented by the hexadecimal color code #052F58, is a deep, rich shade of blue with historical significance. It was first synthesized in the early 18th century and quickly gained popularity due to its stability, intensity, and affordability. The color is a coordination compound of iron and cyanide and is notable for its use in pigments, paints, and inks. In art, Prussian Blue has been used by renowned artists such as Hokusai and Van Gogh. Chemically, it's known as ferric ferrocyanide. Its unique properties have also led to applications in medicine, such as treating heavy metal poisoning. This color evokes feelings of stability, trustworthiness, and sophistication.

The hex color #052F58, a deep shade of Prussian Blue, presents considerable accessibility challenges, particularly when used as a text color. Due to its low luminance value, it requires very light foreground colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #052F58 for text or interactive elements, careful consideration must be given to the background color. White or very pale yellows, greens, or blues are generally suitable. Tools like contrast checkers can help ensure compliance. For non-text elements like icons or graphical components, a contrast ratio of 3:1 is the minimum requirement. Therefore, designers and developers should always prioritize accessibility when incorporating this color into user interfaces, making informed choices to accommodate users with visual impairments.
