About International Klein Blue

It was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, and patented in 1957.

International Klein Blue is not just a color; it's a cultural icon, symbolizing art, innovation, and boundless creativity.

The color is often associated with depth, spirituality, and the infinite expanse of the sky and sea.

The hex color #091CAB, also known as International Klein Blue, presents some accessibility challenges due to its deep, saturated nature. When used as a foreground color, it requires careful consideration of contrast ratios against background colors. To ensure readability and usability for individuals with visual impairments, including those with low vision or color blindness, it's crucial to pair it with light colors. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Avoid using this color for critical interactive elements without sufficient contrast. Testing color combinations with accessibility tools is highly recommended to validate compliance and ensure an inclusive user experience. Consider providing alternative color schemes for users who may have difficulty perceiving this specific hue.
