International Klein Blue
About International Klein Blue
International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. The visual impact of IKB comes from its reliance on ultramarine pigment, as well as Klein's matte, synthetic resin binder, which suspends the color pigment and allows the pigment to maintain as much of its original qualities and intensity as possible. The color is highly saturated and evokes feelings of depth, transcendence, and boundlessness. It's frequently used in art, design, and fashion to create a bold and memorable visual impact. The creation and trademarking of IKB underscore the intersection of art, commerce, and intellectual property in the modern era.
The hex color #031fb1, a deep and vibrant blue known as International Klein Blue, presents significant accessibility challenges. Its low luminance value creates very poor contrast against light backgrounds, making text or interactive elements nearly illegible for users with visual impairments. According to WCAG guidelines, this color fails even the most lenient contrast ratio requirements. To improve accessibility, it's essential to pair this color with a very light background, such as white (#FFFFFF) or a very pale yellow. Alternatively, using a much darker shade of blue or even a neutral dark gray for the background would drastically improve readability and usability for a wider range of users, including those with low vision or color blindness. Proper contrast ensures that content is perceivable and understandable by everyone.
