General Information about Prussian Blue

Prussian Blue, represented by the hexadecimal color code #043153, is a dark shade of blue with a rich history and diverse applications. Chemically, it is a complex iron cyanide pigment, known for its intense color and permanence. Historically, it was one of the first synthetic blue pigments, discovered accidentally in the early 18th century. Its creation revolutionized the art world, providing a more affordable and stable alternative to natural ultramarine, which was derived from the semi-precious stone lapis lazuli.

Its deep and captivating hue continues to be valued across various industries.

The hex color #043153, a deep shade of Prussian Blue, presents significant accessibility challenges, especially in web design. Due to its low luminance, it requires careful consideration when used for text or interactive elements. Insufficient contrast between this color and lighter backgrounds can make content difficult to read, particularly for users with visual impairments. To ensure accessibility, it's crucial to adhere to WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using online contrast checkers can help verify compliance. Pairing #043153 with very light colors like #FFFFFF or #F0F0F0 is advisable to meet accessibility requirements. Also, avoid using it for crucial interactive elements without proper visual cues, as users might miss them. Providing alternative styling options can greatly enhance the user experience.
