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 sought to create a blue that captured the essence of the sky and the sea. He registered this color under patent in 1957. What makes IKB unique is not just its specific shade, but also its matte finish. Klein achieved this distinctive quality by suspending pure ultramarine pigment in a synthetic resin. The lack of sheen enhances the color's intensity, making it appear almost ethereal. IKB has since become a recognizable and iconic color, used in art, fashion, and design to evoke feelings of depth, spirituality, and modernity. The intense saturation and matte texture set it apart from other blues, giving it a unique visual impact.

The hex color #0022a1, a deep and saturated blue, presents significant accessibility challenges, particularly concerning color contrast. When used as a background, it necessitates very light text colors, such as white or very pale yellows, to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Failing to meet these ratios can exclude users with visual impairments, including those with low vision or color blindness. Designers should use contrast checking tools to verify compliance. Furthermore, relying solely on color to convey information is discouraged. Consider adding supplementary cues like text labels or icons to ensure inclusivity for all users. Careful consideration of color combinations and contrast is essential for creating an accessible and user-friendly experience.
