General Information about Prussian Blue

Prussian Blue, represented by the hexadecimal color code #002E5C, is a deep, dark shade of blue with a rich history. It was first synthesized in the early 18th century and quickly became a popular pigment due to its vibrant color and relative low cost. Chemically, it's a complex iron cyanide compound. This color is often associated with elegance, sophistication, and stability. In color psychology, blue is known to evoke feelings of calmness, trust, and security. Its depth and intensity make it suitable for various applications in design, art, and fashion. Understanding the properties and associations of Prussian Blue can help designers and artists use it effectively to achieve their desired aesthetic and emotional impact. It is important to note that, despite its common use, Prussian Blue pigment can degrade over time or with exposure to certain chemicals.

The color #002E5C, also known as Prussian Blue, presents some accessibility challenges, especially when used as text on a white background. Its low luminance value of approximately 5.9 means there's insufficient contrast for readability according to WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, using #002E5C for text requires careful consideration. Pairing it with very light colors like whites or very light yellows can help improve contrast. For UI elements like buttons, ensuring sufficient contrast for both text and non-text elements is crucial. When using it as a background color, ensure that the foreground elements have high contrast to remain accessible to individuals with visual impairments. Tools like contrast checkers are highly recommended during the design process.
