General Information about International Klein Blue
International Klein Blue (IKB), with the hex code #0239B2, is a deep blue hue first synthesized by the French artist Yves Klein. It's renowned for its intense saturation and unique matte finish, achieved by suspending pure color pigment in a synthetic resin. Klein registered this color as a trademark in 1957, solidifying its place in art history. The color evokes feelings of depth, infinity, and the immaterial. In the RGB color model, #0239B2 is composed of 0.8% red, 22.4% green, and 69.8% blue. In the CMYK color model, it consists of 99% cyan, 66% magenta, 0% yellow, and 30% black. Its spectral reflectance properties contribute to its distinct visual impact, making it instantly recognizable and highly valued in artistic and design contexts.
The color #0239B2, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its dark hue results in low contrast against light backgrounds, making text and interface elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. To ensure accessibility, it's recommended to pair this color with very light shades or to use it sparingly for decorative elements. When used for text, a larger font size and increased letter spacing can improve readability. Additionally, providing alternative color schemes that offer higher contrast is beneficial for users with specific visual needs. Designers should also consider the impact on users with color blindness and ensure that information is not conveyed solely through color.
