About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade of blue was developed as part of Klein's search for a color that best represented his concept of pure space and the immaterial. Klein patented IKB in 1957 to maintain its purity and distinctiveness. The color is characterized by its intense saturation and ultramarine pigment, which gives it a unique visual impact. Due to its vibrancy, IKB is often associated with feelings of depth, creativity, and infinity. It stands out in design and art due to its specific chemical formulation and the philosophical intentions behind its creation, making it more than just a color, but a statement.

The hex color #002DB3, also known as International Klein Blue, presents several accessibility considerations. Due to its deep, saturated hue and low luminance value, it can pose challenges for users with visual impairments or color blindness. Using this color as the sole means of conveying important information is not recommended. The contrast ratio against white (#FFFFFF) is relatively low, potentially failing WCAG (Web Content Accessibility Guidelines) requirements for sufficient contrast. For optimal accessibility, it's essential to pair this color with lighter text or background colors to ensure readability. Avoid using it for small text or intricate graphics. Furthermore, consider providing alternative visual cues or text descriptions to ensure that the information is accessible to all users, regardless of their visual abilities. Testing with accessibility evaluation tools is strongly advised.
