This pigment was accidentally discovered in Berlin around 1706 and quickly became a widely used pigment in paintings, dyes, and inks. Its chemical composition is complex, involving iron cyanide compounds, which contribute to its unique and intense color.

The hex color #073157, a deep shade of Prussian Blue, presents significant accessibility challenges, particularly when used as text on a white or light-colored background. Its low luminance contrast can make it difficult for individuals with visual impairments, including those with low vision or color blindness, to distinguish the text from the background. To ensure accessibility, it's crucial to use a contrasting color for text or interactive elements. A light yellow or off-white would provide sufficient contrast according to WCAG guidelines. When using #073157 for larger elements, such as backgrounds or decorative accents, consider pairing it with lighter shades of blue or complementary colors to maintain visual interest while ensuring legibility. Adequate spacing and sizing can also improve readability for all users, regardless of visual ability.
