International Klein Blue
About International Klein Blue
International Klein Blue, represented by the hex code #0533af, is a deep and intense shade of blue known for its captivating and ultramarine appearance. This color was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, aiming to achieve the most vivid and pure expression of blue. Klein patented the color under the name International Klein Blue (IKB) in 1957. It is a specific hue of blue that is achieved by suspending pure color pigment in a clear synthetic resin, which retains the color's brilliance because the pigment particles are not diluted by a binder. It is highly regarded in the art world for its profound visual impact and is often associated with spirituality and infinity.
The hex color #0533af, also known as International Klein Blue, presents accessibility challenges due to its low luminance. When used as a foreground color on a white background, it may not meet WCAG (Web Content Accessibility Guidelines) AA standards for contrast ratio. Specifically, the contrast ratio is significantly below the required 4.5:1 for normal text and 3:1 for large text. Therefore, it's crucial to pair this color with very light or white text to ensure readability for users with visual impairments. Designers and developers should utilize contrast checker tools to verify the contrast ratio and make necessary adjustments. Alternatives include using a lighter shade of blue or a contrasting color like yellow or orange to improve accessibility. Furthermore, consider providing alternative color schemes for users who may have color vision deficiencies.
