Prussian Blue
General Information about Prussian Blue
Prussian Blue, represented by the hexadecimal color code #053452, is a dark shade of blue with a rich history. This pigment was accidentally discovered in Berlin around 1706 and quickly became a popular color due to its stability and affordability. Chemically, it's a complex iron cyanide compound. Prussian Blue has been widely used in various applications, including paints, inks, and dyes. Its deep, intense hue has made it a favorite among artists, such as Hokusai, who famously used it in his iconic woodblock prints. In modern times, Prussian Blue is valued for its use in the production of blueprints and as a medication to treat certain types of metal poisoning. Its enduring presence across art, science, and industry demonstrates its significant historical and practical value.
The color #053452, a deep shade of Prussian Blue, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value of approximately 3% means that text rendered in this color requires a very light foreground color to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text. Using white (#FFFFFF) as the foreground color achieves a contrast ratio of about 15:1, which exceeds the requirement. However, any foreground color darker than #A0A0A0 might fail accessibility standards. When using this color for interactive elements such as buttons or links, consider providing additional cues beyond color alone, such as underlines or icons, to help users perceive these elements more easily. Also, avoid using #053452 for essential information without a high contrasting alternative, as it might be missed by those with low vision or color blindness. Proper implementation of ARIA attributes can further enhance accessibility by providing semantic information to assistive technologies.
