Prussian Blue
General Information about Prussian Blue
Prussian Blue, represented by the hex code #01315c, is a dark shade of blue, known for its rich and deep tone. It is a pigment that was first synthetically produced in the early 18th century and quickly gained popularity due to its stability, intensity, and relatively low cost compared to other blue pigments available at the time, such as ultramarine. Chemically, it is a complex iron cyanide compound. It's not just favored for its aesthetic qualities, but also for its use in various applications beyond art. The color has a historical significance because of it's adoption across various military uniforms in the Prussian army and other states from 18th century onwards. In terms of color theory, Prussian Blue is a cool color, often associated with depth, stability, and trust. Due to its darkness, it is essential to consider contrast when using it in designs, especially in web accessibility, ensuring readability of text and other elements.
The hex color #01315c, a deep shade of Prussian Blue, presents specific accessibility considerations for web developers. When used as a background color, it requires careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Lighter shades of text, such as white (#ffffff) or very light grays, are typically necessary to meet these contrast requirements. Using tools to measure contrast ratios is crucial. Also, avoid using this color for elements that rely solely on color to convey information, ensuring that alternative cues, such as text labels or icons, are present. When using this color for interactive elements like buttons or links, consider providing clear visual feedback on hover or focus states to aid users with visual impairments or those using assistive technologies. Thoughtful implementation of color combinations and additional indicators greatly enhances the accessibility of web content utilizing this deep blue hue.
