About International Klein Blue
International Klein Blue, often referred to 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 patent for maintaining the color's brilliance through a synthetic resin suspension. This particular shade of blue is renowned for its captivating depth and intensity. Klein used this color extensively in his art, seeking to evoke feelings of boundlessness and transcendence. The color has since become iconic, associated with creativity, innovation, and a sense of the infinite. It is often used in design and art to evoke these same feelings of depth and the sublime.
The hex color #0029b4, also known as International Klein Blue, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it's crucial to pair it with text that has sufficient luminance contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). White text (#FFFFFF) provides a good contrast against #0029b4, ensuring readability for most users, including those with visual impairments. Avoid using dark or similarly saturated colors for text on this background, as it can cause eye strain and make content difficult to perceive. Tools like WebAIM's contrast checker can help verify sufficient contrast ratios.
