About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. The color's visual impact comes from its heavy reliance on ultramarine pigment, as well as Klein's matte, synthetic resin binder, which allows the pigment to maintain its brilliance. The color was patented by Klein in 1957. The unique and captivating nature of IKB has made it a recognizable and influential color in the art world, and design in general, representing creativity and innovation. Its intensity and depth offer a sense of intrigue and visual stimulation, making it a popular choice for artists and designers looking to make a bold statement.

The hex color #052AAF, also known as International Klein Blue, presents several accessibility challenges, particularly in web design. Its high saturation and relatively low luminance (brightness) mean that using it as a primary background color can cause eye strain and make it difficult for users with visual impairments to read text effectively. When using this color, it's crucial to ensure sufficient contrast between the text and the background. A light text color like white or a very pale yellow is recommended to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Also avoid using this color for small elements or intricate details, as it can be difficult to discern for users with low vision. When implementing this color consider providing alternative color schemes for users who may need them.
