Prussian Blue

#00334E

General Information about Prussian Blue

Prussian Blue, represented by the hex code #00334e, is a deep, rich shade of blue with subtle green undertones. It derives its name from the pigment first synthesized in the early 18th century, known for its stability, intensity, and relatively low cost. Chemically, Prussian Blue is a complex iron cyanide compound. The color is widely used across various industries, including painting, dyeing, and printing. In digital contexts, #00334e offers a sophisticated and calming presence, often associated with depth, stability, and trustworthiness. Its relatively low brightness requires careful consideration of contrast when used with text or other interactive elements, making accessibility a key factor in its effective application. In terms of color theory, Prussian Blue resides in the cool spectrum, making it suitable for backgrounds and accent elements where a sense of tranquility or formality is desired.

The hex color #00334e, a deep shade of Prussian Blue, presents some accessibility challenges, particularly for text. Its low luminance value of 0.026 means that it requires very light text to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal-sized text and 3:1 for large text (14pt bold or 18pt regular). Given this color's darkness, only very light colors like white (#FFFFFF) or near-white shades will likely meet these requirements. When using #00334e for backgrounds or other design elements, careful consideration should be given to the color of any text or interactive elements placed on top. It's essential to test the contrast ratio using accessibility tools to ensure compliance and provide a positive user experience for individuals with visual impairments. Also, avoid using this color as a primary color for data visualization as it might be difficult to distinguish from other dark shades. Using it for large graphical elements or as an accent color is generally safer.
