About International Klein Blue

International Klein Blue, identified by the hexadecimal color code #0920B1, is a deep, saturated blue hue known for its unique intensity and visual impact. This color was specifically developed by the French artist Yves Klein in collaboration with a Parisian paint supplier. Klein sought to create a blue that captured the essence of the sky and the sea, aiming for a pure, ultramarine pigment devoid of any distracting gloss or surface texture. The resulting color was officially patented as International Klein Blue (IKB) in 1957. Its distinctive matte finish and profound depth have made it a recognizable and influential color in the art world. It is often associated with concepts of spirituality, infinity, and the immaterial, reflecting Klein's artistic vision.

The hex color #0920B1, also known as International Klein Blue, presents significant accessibility challenges due to its low luminance. When used as a foreground color on a white background, it fails to meet the contrast ratio requirements set by WCAG (Web Content Accessibility Guidelines) for both normal text (4.5:1) and large text (3:1). This means that users with visual impairments, such as those with low vision or color blindness, may struggle to read text displayed in this color. To improve accessibility, it is crucial to pair #0920B1 with a very light background color or to use it for purely decorative elements where readability is not essential. Alternatively, using a much lighter shade of blue or a contrasting color like yellow or white for text on a #0920B1 background can significantly enhance readability and ensure a more inclusive user experience. Always prioritize sufficient contrast to cater to a diverse range of users and adhere to accessibility standards.
