General Information

Prussian Blue, represented by the hex code #03355A, is a dark shade of blue with a rich history and significant presence in art and design. It was first synthesized in the early 18th century and quickly became a popular pigment due to its stability, intensity, and relatively low cost. The color is known for its deep, slightly greenish undertone, reminiscent of the uniforms worn by the Prussian army, hence its name. In the RGB color model, #03355A consists of 1.2% red, 20.8% green, and 35.3% blue. It has a calming and sophisticated feel.

The hex color #03355A, also known as Prussian Blue, presents some accessibility challenges, particularly when used for text or interactive elements. Its dark nature means that it requires a light-colored foreground 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. Using a color like white (#FFFFFF) or a very light shade of yellow or beige as the foreground color could provide adequate contrast. Careful consideration should be given to users with visual impairments, who may find it difficult to distinguish between similar dark shades. Testing with accessibility tools and gathering feedback from users are essential steps in ensuring inclusivity. Also avoid using this color as background color with dark text.
