General Information about Prussian Blue

Prussian Blue, represented by the hex code #002D5D, is a deep, rich shade of blue with historical significance in art and chemistry. It was one of the first synthetically produced pigments, discovered accidentally in the early 18th century. Its unique chemical structure gives it exceptional lightfastness and color intensity, making it a valued pigment for paints, inks, and dyes. The color's name derives from its widespread use in Prussian military uniforms. Characterized by its strong and unwavering hue, Prussian Blue has been adopted across various fields, ranging from artistic creations to technical applications. It's known for its stability and resistance to fading, which makes it a popular choice in permanent mediums. In digital contexts, it presents a sophisticated and authoritative impression.

The hex color #002d5d, also known as Prussian Blue, presents some accessibility challenges, particularly in text applications. Its dark nature necessitates careful consideration of contrast ratios against lighter backgrounds to ensure readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Prussian Blue for text, pair it with a very light color like white or a pale yellow to meet these standards. Insufficient contrast can make content difficult or impossible to perceive, thereby excluding users with low vision or color blindness. Furthermore, avoid using this color as the sole means of conveying information, as colorblind users may not be able to distinguish it from other dark hues. Consider supplementing color cues with text labels or icons to ensure inclusivity.
