Prussian Blue
General Information about Prussian Blue
Prussian Blue, represented by the hexadecimal color code #0A3259, is a deep and rich shade of blue. It derives its name from the pigment originally made by heating potassium ferrocyanide with iron salts. This pigment was first produced in the early 18th century and quickly gained popularity due to its stability and vibrant color. Prussian Blue is known for its strong tinting strength and is used in various applications, including paints, inks, and dyes. In digital contexts, #0A3259 provides a sophisticated and calming visual element, often associated with professionalism, trust, and stability. However, its darkness requires careful consideration of contrast to ensure accessibility, especially in text-based applications.
The hex color #0a3259, a shade of Prussian Blue, presents some accessibility challenges, particularly in text applications. Its low lightness value of 11% means it has weak contrast against standard white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color likely falls short, making text difficult to read for users, especially those with visual impairments. To improve accessibility, consider using #0a3259 with lighter background colors or using it for larger graphical elements where readability is less critical. Also, avoid using this color to convey critical information without providing sufficient contrast or alternative cues.
