About Prussian Blue
Prussian Blue, also known as Berlin Blue or iron(III) hexacyanoferrate(II), is a deep blue pigment with the chemical formula Fe7(CN)18. It's notable for being one of the first modern synthetic pigments. Discovered accidentally in the early 18th century, it quickly became a popular color for artists and dyers due to its intense color, stability, and relatively low cost. Prussian Blue is a complex inorganic compound where iron ions are coordinated with cyanide ligands, creating a unique structure that absorbs light in a specific region of the spectrum, resulting in its characteristic blue hue. It has applications ranging from paints and inks to medical treatments and industrial processes.
The color #003157, a deep shade of Prussian Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates light-colored text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. Tools like contrast checkers can help verify compliance. Using this color for interactive elements like buttons or links requires careful consideration. Providing clear visual cues beyond color alone, such as underlines or icons, is essential for users with color vision deficiencies. Thoroughly testing the color scheme with various accessibility evaluation tools and user feedback is crucial to ensure an inclusive user experience.
