About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade of blue was synthetically created and trademarked by Klein as a means to maintain the color's fidelity and protect its unique visual impact. Klein believed this particular blue best conveyed his concept of boundless space and the immateriality of art. Chemically, it's a matte ultramarine pigment. Its intense saturation and depth make it a visually striking color, often associated with creativity, artistic expression, and a sense of the infinite. IKB's unique status in the art world has made it a popular choice for designers seeking to create a sense of elegance or sophistication. It is also seen as a symbol of modern art.

The hex color #0814ac, also known as International Klein Blue, presents some accessibility challenges due to its deep, saturated nature. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. This deep blue necessitates a very light background, such as white or a pale yellow, to achieve adequate readability. Conversely, using #0814ac as a background color requires light text, such as white or a very pale tint, to ensure legibility. When incorporating this color into a user interface, it's advisable to use contrast checking tools to verify compliance with accessibility standards, ensuring that all users, including those with visual impairments, can easily perceive and interact with the content. Using it with darker tones can cause eye strain.
