About International Klein Blue

International Klein Blue (IKB), represented by the hexadecimal color code #0627ae, is a deep, vivid blue hue developed by the French artist Yves Klein. Klein patented this color in 1957 to ensure its unique intensity and brilliance would be preserved. IKB achieves its striking appearance through the use of a synthetic ultramarine pigment suspended in a clear, matte synthetic resin, which allows the pigment's inherent luminosity to shine through. It is not only a color but also a statement of artistic expression, often associated with spirituality and boundless space. Its distinctive quality has made it a significant element in modern and contemporary art, design, and fashion.

The hex color #0627ae, also known as International Klein Blue (IKB), presents significant accessibility challenges, particularly concerning color contrast. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. Using it for interactive elements like buttons or links needs careful consideration, ensuring that hover and focus states also maintain adequate contrast. It's crucial to test the color combination with accessibility tools to verify compliance and provide an inclusive experience. Due to its deep, saturated nature, it might not be suitable for large blocks of text. Consider using it sparingly, perhaps for headings, accents, or graphical elements, paired with more accessible background and text colors.
