International Klein Blue
About International Klein Blue
International Klein Blue, abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine, as well as Klein's artistic use of the color applied with a synthetic resin binder, which retains the color's brilliance and powdered appearance. Klein patented this process. This particular shade of blue is renowned for its intensity and unique matte finish, which contributes to its distinctive visual appeal. The color is often associated with concepts like infinity, spirituality, and the boundless expanse of the sky and sea. It became Klein's signature color and played a significant role in his artistic expressions, particularly in his monochrome paintings and sculptures.
The hex color #021fb2, also known as International Klein Blue, presents significant accessibility challenges due to its low luminance. Its stark contrast against lighter backgrounds may be suitable for users with good vision. However, it fails WCAG's AA and AAA standards for normal and large text sizes when paired with white (#ffffff). For optimal accessibility, it is recommended to use this color with very light shades of gray or yellow to ensure sufficient contrast for users with visual impairments. Designers should avoid using it for crucial elements such as form fields or call-to-action buttons without careful consideration of contrast ratios. Tools like contrast checkers can help assess the compliance of color combinations and make necessary adjustments to meet accessibility requirements.
