Prussian Blue
General Information about Prussian Blue
Prussian Blue, represented by the hexadecimal color code #003655, is a deep and rich shade of blue with historical significance. It was first synthesized in the early 18th century and quickly became a popular pigment due to its intense color and relative affordability. Chemically, it is a complex iron cyanide compound. Prussian Blue has been used extensively in art, notably in paintings by artists like Hokusai and Van Gogh. Beyond its artistic applications, it has also found use in medicine as an antidote for certain types of metal poisoning, specifically thallium and cesium. The color is associated with depth, stability, and formality, making it a popular choice in corporate branding and design.
The hex color #003655, a deep shade of Prussian Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires light-colored text to ensure readability. 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. Using a color contrast checker is highly recommended to verify compliance. Given its darkness, #003655 can be effective for large headings or decorative elements where readability is less critical. However, for body text or interactive elements like buttons, pairing it with colors such as white (#FFFFFF) or very light grays is essential. Failure to meet contrast standards can exclude users with visual impairments, reducing the usability of the design.
