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 patented this color to maintain its unique intensity and association with his artistic vision. The color is achieved by suspending pure ultramarine pigment in a clear synthetic resin, which allows the pigment to retain its brilliance without being dulled by a binding medium. IKB is renowned for its matte finish and striking visual impact, often described as having a sense of depth and transcendence. Klein used IKB extensively in his monochrome paintings and sculptures, aiming to evoke spiritual and emotional responses in viewers. This specific blue has since become an iconic color in art and design, symbolizing innovation and artistic expression. The color #0316B1 has a RGB value of R:3, G:22, B:177 and a CMYK value of C:0.98, M:0.87, Y:0.00, K:0.31.

International Klein Blue (#0316B1) presents accessibility challenges due to its deep, saturated nature. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA standards. Using a color contrast checker is essential to verify compliance. Avoid pairing this blue with mid-tone colors, as they will likely fail contrast requirements. Consider using it sparingly for decorative elements rather than extensive text areas. Designers should provide alternative high-contrast themes or options for users with visual impairments. It's also important to test the color on various devices and screen settings to ensure consistent visibility.
