About Prussian Blue (#023655)

Prussian Blue, chemically known as ferric ferrocyanide, is a deep blue pigment with the chemical formula Fe7(CN)18. It was accidentally discovered in Berlin around 1706 by dye maker Johann Jacob Diesbach. Initially used as a pigment for paints and inks, Prussian Blue gained widespread popularity due to its intense color and relative lightfastness. It has been historically employed in various applications, including fine art, textile dyeing, and even as a medication to treat certain types of heavy metal poisoning. The color's rich history and unique properties have made it a significant pigment in both the artistic and industrial realms. Its deep hue evokes feelings of stability, depth, and sophistication, making it a popular choice for design applications seeking a sense of timeless elegance. It is a very strong and reliable pigment that offers great value.

The hex color #023655, also known as Prussian Blue, presents some accessibility challenges. Its dark nature results in low contrast against standard light backgrounds, which can make text or interactive elements difficult to read for users, especially those with visual impairments. According to WCAG guidelines, sufficient contrast is essential for readability. To improve accessibility, consider using a lighter color for text or interactive elements placed on a #023655 background. Alternatively, pairing #023655 with a much lighter accent color can help create visual separation and improve the overall user experience. Tools for checking color contrast ratios are readily available online and should be consulted during the design process to ensure compliance with accessibility standards, such as WCAG AA or AAA levels. Remember that perceived contrast can also be affected by factors such as font size and weight, so these should also be taken into account.
