Prussian Blue

General Information about Prussian Blue

Prussian Blue, represented by the hexadecimal color code #012F5C, is a deep, rich shade of blue with historical significance. It was originally produced synthetically in the early 18th century and quickly gained popularity due to its intensity and affordability. Chemically, it is an iron hexacyanoferrate complex. In art, Prussian Blue is valued for its strong tinting power and is often used in painting and printing. The color name derives from Prussia, where the pigment was first made. The hex code #012F5C breaks down into Red: 1, Green: 47, Blue: 92. Its RGB values indicate a strong presence of blue and very little red, which positions it distinctly within the blue spectrum. This color is often associated with depth, stability, and sophistication.

The hex color #012F5C, a deep shade of Prussian Blue, presents several accessibility considerations, particularly for text and user interface elements. Its low luminance necessitates careful selection of contrasting colors to ensure readability. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. When using #012F5C as a background, it is essential to pair it with light text colors, such as white (#FFFFFF) or light yellow (#FFFFE0), to meet the minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Conversely, if #012F5C is used for text, a very light background color is needed. Furthermore, avoid using this color alone to convey important information, as color blindness can affect its perception. Instead, supplement with icons or text labels for clarity.
