International Klein Blue
About International Klein Blue
International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine pigment and a unique matte, synthetic resin binder which allows the pigment to maintain its intensity and brilliance. The color was specifically created by Klein to express his artistic vision, aiming to evoke feelings of pure space and limitlessness. He described this particular shade of blue as having "no dimensions," setting it apart from other colors due to its intense saturation. The color was officially patented by Yves Klein in 1957. It has since become synonymous with Klein's art and is frequently associated with modernity, innovation, and depth.
The hex color #0221B2, also known as International Klein Blue, presents some accessibility challenges, particularly in web design. Its dark hue means that careful consideration must be given to text and background color combinations. To ensure readability and inclusivity, it's essential to use a light color for text placed on a #0221B2 background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) AA standards. For AAA compliance, aim for a contrast ratio of 7:1 for normal text and 4.5:1 for large text. Tools like contrast checkers can help verify compliance. Avoid using this color for essential interactive elements or information without sufficient contrast, as it may be difficult for users with visual impairments to perceive. When using this color as a background, ensure interactive elements have clear visual cues to show their state (e.g., hover, focus).
