It is named after the pigment first created in the early 18th century, which was widely used in paintings, dyes, and inks. The color is composed of 0% red, 21.6% green, and 34.1% blue. In the RGB color model, it is (0, 55, 87). Its CMYK values are 100% cyan, 37% magenta, 0% yellow, and 66% black. Prussian Blue is often associated with qualities such as authority, stability, and intelligence, making it a popular choice for corporate branding and designs aiming to convey trustworthiness. Its low lightness value also makes it a suitable background color for designs where text needs to stand out.

The hex color #003757, a deep shade of Prussian Blue, presents significant accessibility challenges, especially in web design. Its low lightness value results in a poor contrast ratio against standard white backgrounds, making text difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To improve accessibility, consider using a lighter text color such as white or a very light gray to ensure sufficient contrast. Alternatively, this color can be paired with very bright background colors such as yellow or orange. Also, avoid using this color for critical elements like buttons or links without careful consideration of the surrounding colors. Tools like contrast checkers are invaluable for assessing and improving the accessibility of color combinations. Meaning should never be conveyed by color alone.
