It was accidentally discovered in the early 18th century and quickly became a popular pigment due to its stability and relatively low cost. Chemically, it's a complex iron cyanide compound. In color psychology, Prussian Blue is associated with intellect, stability, and authority. It evokes feelings of calmness, trustworthiness, and formality.

The hex color #022F5B, a deep Prussian Blue, presents some accessibility challenges due to its low luminance. When used as a background color, it's crucial to ensure that the foreground text provides sufficient contrast to meet WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular). Light shades of yellow, white, or even carefully chosen lighter blues or greens could serve as effective foreground colors. Tools like WebAIM's contrast checker can assist in verifying adequate contrast. Furthermore, avoid using this color for critical interactive elements without clear visual cues beyond color alone, as users with color vision deficiencies may struggle to perceive them. Consider adding borders, icons, or text labels to enhance usability for all users. When using this color be careful to follow accessibility best practices. This allows all users to be able to use the content.
