About Prussian Blue (#053658)
Prussian Blue, represented by the hexadecimal color code #053658, is a deep and rich shade of blue with historical significance. It was first synthesized in the early 18th century and quickly became a popular pigment due to its stability, intensity, and relatively low cost. Chemically, it is a complex iron cyanide compound. Prussian Blue has been used extensively in paints, dyes, and inks, and it's notable for its use in blueprints, where it gives the characteristic blue color to the paper. Its color is due to the charge transfer between iron ions in the compound. In color theory, Prussian Blue is considered a cool color, often associated with calmness, depth, and formality. It evokes feelings of serenity, trust, and stability. It sits between blue and cyan in the color spectrum.
The color #053658, a deep shade of Prussian Blue, presents considerable accessibility challenges in web design. Its low luminance of approximately 3% results in very poor contrast against standard white backgrounds. According to WCAG guidelines, the contrast ratio falls far below the minimum requirement of 4.5:1 for Level AA compliance. This means that text rendered in #053658 on a white background would be difficult for users with moderate visual impairments to read. To enhance accessibility, it is crucial to pair #053658 with much lighter colors. White (#FFFFFF) should be avoided unless the text is significantly large and bold, or accompanied by enhancements like shadows or outlines. Better choices include light yellows (#FFEC8B), very pale blues (#ADD8E6), or light grays (#D3D3D3), ensuring a contrast ratio that meets accessibility standards. Consider using contrast checking tools during the design process to validate color combinations and ensure usability for all users.
