International Klein Blue

#0526AE

General Information

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. It is characterized by its intense saturation and ultramarine pigment. Klein registered this color as a trademark in 1957. The color's unique visual impact stems from its high concentration of pigment, which creates a sense of depth and intensity. It is achieved through a specific mixture involving a synthetic resin binder that allows the pigment to retain its pure, unadulterated color. IKB has become an iconic color in art and design, often associated with innovation, creativity, and a sense of the infinite. Its striking appearance makes it a popular choice for artists, designers, and brands seeking to make a bold statement.

The hex color #0526ae, known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value results in poor contrast against light backgrounds, making text and graphical elements difficult to perceive. Adhering to WCAG guidelines is crucial when using this color. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) and user interface components. Pairing #0526ae with very light colors like white or pale yellow is essential to meet these standards. Avoid using it for critical information or interactive elements without careful consideration of contrast. Providing alternative color schemes or allowing users to customize colors can greatly improve accessibility for individuals with varying visual needs.
