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. It is renowned for its remarkable saturation and distinctive matte finish. Klein registered this color as a trademark in 1957, solidifying its place in art history. The unique quality of IKB comes from the synthetic resin binder used, which allows the pigment to maintain its vividness without becoming dull or reflective. The color is not just a visual phenomenon, but also associated with Klein's artistic exploration of immateriality and the infinite. Today, IKB is still celebrated in the art world and beyond for its intense, captivating, and instantly recognizable presence.

The color #0717AD, a deep blue, presents significant accessibility challenges, particularly in text applications. Its low luminance value of approximately 2.5% creates very little contrast against dark backgrounds, rendering it nearly invisible. When used with white text, the contrast ratio is also low, failing to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (4.5:1) or even large text (3:1). To improve accessibility, consider pairing #0717AD with significantly lighter colors like whites, light yellows, or pale blues. Alternatively, use it sparingly for purely decorative elements where legibility is not critical. In interfaces, avoid using it for important interactive elements without adequate contrast, which could lead to a poor user experience for individuals with visual impairments. Careful consideration of color contrast is essential when incorporating #0717AD into designs.
