International Klein Blue
General Information about International Klein Blue
International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Its visual impact comes from its heavy reliance on ultramarine pigment, as well as Klein's matte, synthetic resin binder, which suspends the color pigment and gives the paint the ability to retain the hue’s original qualities. Klein registered this recipe as a trademark in 1957. It is a vivid, strong color. Due to it's artistic roots, it is often associated with creativity, inspiration, and artistic expression. The color is mostly used in web design, fashion and art.
The hex color #0039A6, also known as International Klein Blue, presents certain accessibility considerations for web developers. Due to its relatively dark hue, it's crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #0039A6, pairing it with lighter colors like white (#FFFFFF) or light yellows can help achieve this required contrast. Tools are available to check contrast ratios to ensure compliance. Additionally, providing alternative visual cues besides color, like underlines for links, can significantly enhance usability for users with color vision deficiencies. Always test color combinations with accessibility checkers.
