About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein sought to develop a blue that best expressed his concepts of spirituality and art. The color is achieved by mixing ultramarine pigment with a synthetic resin binder, allowing the pigment to maintain its intensity and vibrancy. IKB is a registered trademark and is often associated with modern art and minimalist design. Its unique depth and intensity make it a visually striking and recognizable color. In digital representation, IKB is often approximated by the hexadecimal color code #0715AD. Its intense nature makes it suitable for artistic and design purposes where a powerful visual impact is desired.

The hex color #0715ad, representing International Klein Blue, presents significant accessibility challenges, especially in web design. Its dark hue results in low contrast against lighter backgrounds, making text or interactive elements difficult to read for users with visual impairments. To ensure accessibility, it is crucial to use this color with high-contrast text and elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Pairing #0715ad with very light colors like white or pale yellow can help achieve sufficient contrast. Additionally, consider providing alternative color schemes for users with specific visual needs, ensuring that the information remains accessible to everyone, regardless of their visual abilities. Avoid using it as a primary background color for large blocks of text, as this can cause eye strain and reduce readability.
