About International Klein Blue

International Klein Blue, identified by the hexadecimal code #0E1EBC, is a deep, vivid blue hue known for its unique intensity and saturation. It was developed by the French artist Yves Klein in collaboration with a Parisian paint supplier, specifically for his monochrome paintings. The color's distinctiveness arises from its reliance on ultramarine pigment, which provides a pure and intense blue. Klein patented the color in 1957, ensuring its exclusive use in his artistic endeavors. IKB is more than just a color; it is a cultural symbol, representing innovation, creativity, and the pursuit of the infinite. Its intense, almost ethereal quality has made it a popular choice in art, design, and even fashion, where its boldness can add a touch of sophistication and intrigue.

The hex color #0E1EBC, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low contrast when paired with lighter colors like white or yellow. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. To meet the minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text, designers must exercise caution. Using #0E1EBC as a background color necessitates very light text colors to ensure compliance. A contrast checker is highly recommended to verify that the chosen text color provides adequate contrast. Moreover, avoid using this color for crucial interactive elements like buttons or links, unless accompanied by clear visual cues and sufficient contrast. The low luminance of #0E1EBC requires careful consideration to create an inclusive user experience.
