About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein sought to create a blue that was as pure and intense as possible, to evoke a feeling of boundless space and spiritual depth. He patented the color in 1957 to maintain its unique identity. The pigment used in IKB is a synthetic ultramarine pigment, known for its high tinting strength and resistance to fading. IKB has become a signature color associated with Klein's artistic work, appearing in many of his monochrome paintings and sculptures. Its distinct saturation and depth make it recognizable and impactful. Its intense colour made it very iconic to be used for modern art.

The hex color #0920ab, a deep shade of blue, presents several accessibility considerations for web development. When used as a foreground color, it requires careful pairing with a background color that provides sufficient contrast to ensure readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Given the darkness of #0920ab, lighter shades of yellow, white, or light gray would be suitable background choices to meet these contrast requirements. It's also crucial to avoid using this color for essential UI elements without proper contrast, as it could hinder users with visual impairments from interacting with the interface effectively. Testing with accessibility evaluation tools and seeking feedback from users with disabilities is highly recommended to validate the color choices.
