General Information about Prussian Blue (#07355C)

Prussian Blue, represented by the hex code #07355C, is a deep shade of blue known for its rich and intense pigmentation. Historically, it was one of the first synthetically produced blue pigments, discovered accidentally in the early 18th century. Its creation revolutionized the art world by providing artists with a more affordable and readily available alternative to natural ultramarine, which was derived from the rare mineral lapis lazuli and extremely expensive. Prussian Blue is a coordination compound with the formula Fe7(CN)18. It is produced by oxidizing ferrous ferrocyanide salts. The color is widely used in various applications, including dyes, paints, and printing inks. Its chemical composition and stability have made it a valuable asset in various industrial processes as well as its artistic applications.

The hex color #07355C, a deep shade of Prussian Blue, presents specific accessibility challenges, particularly in text-based applications. Its low luminance value means it requires careful pairing with contrasting colors to ensure readability for users, especially those with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. When using #07355C for text, it is crucial to select a light-colored background to meet these contrast requirements. For decorative elements, such as icons or graphical accents, a slightly lower contrast ratio may be acceptable, but careful consideration is still necessary to ensure adequate visibility. Tools such as contrast checkers can be valuable resources for assessing and optimizing color combinations involving #07355C to enhance accessibility.
