About International Klein Blue

International Klein Blue (IKB), also known as #062EAE, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957, even though it was developed in collaboration with a paint supplier. IKB's visual impact comes from its heavy reliance on ultramarine pigment, ensuring the color's purity and intensity. Klein used this color extensively in his monochrome paintings and sculptures, aiming to evoke a sense of boundlessness and transcendence. The color has since become iconic, symbolizing artistic innovation and a unique approach to color theory. It's recognized for its matte finish, which enhances its saturation and depth, setting it apart from other blues.

The color #062eae, also known as International Klein Blue, presents several accessibility challenges. Its low lightness value (approximately 5%) means that text rendered in this color requires extremely light foreground colors to achieve sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using white (#ffffff) text on an International Klein Blue background yields a contrast ratio that meets these standards, but careful consideration must be given to font size and weight. Also, avoid using this color for essential UI elements or informational graphics without proper contrast, as it can be difficult for users with visual impairments to perceive. It's generally advisable to provide alternative high-contrast themes or allow users to customize colors to improve accessibility.
