Prussian Blue
General Information about Prussian Blue
Prussian Blue, represented by the hex code #063251, is a dark shade of blue with historical significance, widely used in paints and dyes. It's a complex inorganic pigment, ferric ferrocyanide, known for its intense color and stability. The color was accidentally discovered in the early 18th century in Berlin and quickly became a popular pigment for artists and textile manufacturers. In the RGB color model, #063251 is composed of 2.4% red, 19.6% green, and 32.7% blue. Its darkness is characterized by relatively low values in each of these components. In the CMYK color model, its values are 93% cyan, 40% magenta, 0% yellow, and 67% black. This makes it a highly saturated, deep blue with a strong presence.
The hex color #063251, a deep shade of Prussian Blue, presents considerable accessibility challenges. Its low luminance necessitates careful consideration of contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. When employing #063251 for text, pairing it with very light colors like #FFFFFF (white) or shades of yellow and orange is crucial to ensure readability for users with visual impairments. Similarly, if it serves as a background, lighter foreground elements are essential. Adequate color contrast is not just about meeting legal requirements; it's about providing an inclusive experience that benefits all users, including those with low vision or color blindness. Tools like WebAIM's Contrast Checker or Accessible Colors can assist in verifying adherence to accessibility standards.
