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, as well as Klein's matte synthetic resin binder, which allows the pigment to maintain its brilliance. Yves Klein registered this paint formula under the name International Klein Blue (IKB) in 1957. This color is visually striking due to its extreme saturation and is often associated with depth, spirituality, and the infinite. This blue shade has been used in various artistic expressions, fashion designs, and even in branding to convey a sense of sophistication and creativity. Its distinctiveness and memorability make it an intriguing choice for artists and designers looking to create a bold and impactful statement.

The hex color #0626AE, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its dark hue demands careful consideration of color contrast ratios to ensure readability for users with visual impairments. When using this color for text or interactive elements, it's crucial to pair it with a very light color for the background or foreground, respectively. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text, as per WCAG guidelines. Insufficient contrast can render content illegible for individuals with low vision or color blindness. Furthermore, relying solely on color to convey information is discouraged. Consider incorporating supplementary cues like text labels or icons to ensure inclusivity. Thoroughly testing the color combination with accessibility tools and diverse user groups is essential to validate its accessibility.
