About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein sought to create a blue that captured the feeling of pure space and the infinite. He collaborated with a Parisian paint supplier to develop a unique matte, synthetic resin-based binder that allowed the pigment to maintain its brilliance and intensity. The color was officially patented as International Klein Blue in 1957. It is known for its captivating depth and its ability to evoke a sense of serenity and vastness. The color is widely used in art, fashion, and design, often to represent concepts of spirituality and the immaterial. Its distinctiveness has made it a recognizable and iconic color in the world of art and culture.

The hex color #0022b2, also known as International Klein Blue, presents certain accessibility challenges, especially in web design. Its dark hue means that it requires light-colored text to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #0022b2 as a background color necessitates careful selection of foreground colors to meet these contrast requirements. White (#ffffff) or very light shades of gray or yellow would be suitable choices. Conversely, using darker shades of text on this background would likely fail accessibility standards, making the content difficult to perceive for users with visual impairments. Proper tools and evaluations should be employed to ensure compliance and optimal user experience.
