About International Klein Blue

International Klein Blue (IKB), represented by the hex code #051BAE, is a deep, vivid shade of blue that was first mixed by the French artist Yves Klein. It's renowned for its intense saturation and unique matte finish, achieved through a special synthetic resin binder that maintains the pigment's purity. Klein registered IKB as a trademark in 1957, solidifying its place in art history. The color is intended to evoke a sense of boundlessness, depth, and immersion, often associated with the sea and sky. IKB quickly became a symbol of modern art and continues to inspire artists and designers across various disciplines. Its particular matte finish is very important to its appearance.

The hex color #051BAE, also known as International Klein Blue, presents some accessibility challenges, especially in web design. Its dark hue means that it requires very light text (white or very light shades of yellow) to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #051BAE as a background color necessitates careful consideration of foreground text color choices and font sizes to meet these guidelines. If contrast requirements are not met, users with visual impairments may struggle to read the content. Always check contrast using online tools to ensure compliance. Additionally, avoid using this color as the sole indicator for interactive elements, such as links, as colorblind users may not be able to differentiate them.
