About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color to maintain its unique status. The color's remarkable intensity and purity arise from its saturation and the fact that it is nearly devoid of green tones. The pigment used to create IKB is a synthetic ultramarine pigment, specifically a very pure form of ultramarine. Because of its striking appearance, IKB has become synonymous with Klein's artwork and is often associated with concepts of infinity, spirituality, and the void. It has seen use in a variety of artistic and commercial applications. The color's unique characteristics make it visually distinct and memorable.

The hex color #022CB2, also known as International Klein Blue, presents several accessibility considerations for web developers. Its dark hue results in a high contrast ratio when paired with white text, generally exceeding the WCAG AA standards for normal text. However, when used with darker shades or smaller text sizes, the contrast may fall below acceptable levels, potentially causing readability issues for users with visual impairments. Furthermore, relying solely on color to convey information is discouraged. Consider providing supplementary cues, such as text labels or icons, to ensure inclusivity for individuals with color vision deficiencies. When using this color for interactive elements, ensure sufficient contrast for hover and focus states to meet WCAG guidelines for interaction accessibility. Proper testing with accessibility tools is highly recommended to validate compliance.
