Prussian Blue
About Prussian Blue (#04335A)
Prussian Blue, represented by the hex code #04335a, is a deep, dark shade of blue with historical significance. It was first synthesized in the early 18th century and quickly became a popular pigment due to its stability, intense color, and relatively low cost. It's a coordination compound with the formula Fe7(CN)18·xH2O, where Fe represents iron, C is carbon, N is nitrogen, and H2O is water. Prussian Blue is found in various applications, ranging from paints and dyes to medicine and analytical chemistry. Its unique structure gives it its distinct color and properties. In art, Prussian Blue has been used by renowned artists such as Van Gogh and Hokusai. The pigment is still widely produced today and is valued for its rich color and versatility.
The hex color #04335a, also known as Prussian Blue, presents significant accessibility challenges, especially when used for text or interactive elements. Its low luminance of 2.1% results in very poor contrast against a standard white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. #04335a fails to meet these standards. Therefore, using #04335a as a text color on a white background is strongly discouraged. When using this color, it's crucial to pair it with a very light color for text or other interactive elements to ensure sufficient contrast. Always test the color combination using accessibility tools to verify compliance with accessibility standards and to provide an inclusive user experience. Consider color blindness as well, and ensure that information isn't conveyed only by color.

Applications
Background Color for Websites
Prussian Blue can be used as a background color in websites or applications where a sense of depth and calmness is desired. For example, a website for financial services or a healthcare provider might use this color to project stability and trust. It should be paired with light text and interactive elements that are easily distinguishable, such as buttons in a bright, contrasting color. Ensure that the lightness difference is high enough to pass accessibility guidelines for people with visual impairments. Moreover, large graphical elements can use the color to suggest tradition and dependability.
Accent Color in Interior Design
In interior design, Prussian Blue can be used as an accent color for walls or furniture. It pairs well with neutral colors like beige, gray, and white. A Prussian Blue sofa in a living room with light-colored walls can create a sophisticated and inviting space. It can also be used for cushions, artwork, or other decorative items to add a touch of elegance and depth to the room. It's essential to balance the darkness of Prussian Blue with lighter elements to prevent the room from feeling too dark or oppressive.
Formal Wear and Corporate Attire
Prussian Blue is a popular color choice for formal wear and corporate attire. A Prussian Blue suit or blazer can project an image of professionalism and competence. It can be paired with a white shirt and a contrasting tie for a classic and sophisticated look. It is an excellent alternative to traditional black or navy suits. In fashion, Prussian Blue can also be used for accessories such as scarves, handbags, or shoes to add a touch of color and style to an outfit. Consider the overall color palette and choose complementary colors to create a harmonious ensemble.
