General Information about Prussian Blue

Prussian Blue, represented by the hexadecimal color code #003050, is a deep, rich shade of blue with a subtle hint of green. It is a dark color, often associated with depth, stability, and sophistication. Historically, Prussian Blue was one of the first synthetic pigments, discovered in the early 18th century. It quickly became a popular color for artists and dyers due to its affordability and colorfastness. The color is made of iron compounds, and is also known under the name Berlin Blue or Paris Blue. It is considered non-toxic for humans. Its chemical stability and intense color also made it valuable in printing inks and paints. Today, Prussian Blue continues to be used in a variety of applications, from art and design to industrial coatings and medical treatments.

The hex color #003050, also known as Prussian Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (ideally white or a very pale shade) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Due to its darkness, avoid pairing it with other dark colors. Additionally, consider users with visual impairments who might have difficulty distinguishing subtle color differences. Providing alternative cues, such as text labels or icons, can improve the usability for those users. When using this color, always prioritize clear visual hierarchy and sufficient contrast to create an inclusive user experience.
