General Information about Prussian Blue

Prussian Blue, represented by the hex code #03365A, is a deep, dark shade of blue. It's a color often associated with sophistication, intelligence, and authority. Historically, Prussian Blue was one of the first synthetically produced pigments, discovered in the early 18th century. Chemically, it's an iron hexacyanoferrate complex. The color is known for its stability and was widely used in paints, inks, and dyes. In color psychology, dark blues like Prussian Blue are often linked to trustworthiness, stability, and knowledge. Its low saturation and brightness give it a serious and formal feel, making it suitable for applications where a sense of professionalism is desired.

The hex color #03365A, also known as Prussian Blue, presents some accessibility challenges. Its low lightness value (around 5%) means that text or elements using this color as a background require very light text colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using white (#FFFFFF) or very light shades of gray would be necessary to meet these requirements. When using this color for interactive elements, consider providing alternative visual cues beyond color alone, such as underlines or icons, to assist users with color vision deficiencies. Proper testing with accessibility tools is crucial to ensure compliance and a positive user experience.
