About International Klein Blue

International Klein Blue (IKB) is a deep blue hue first synthesized by the French artist Yves Klein. The mesmerizing color's visual impact stems from its purity and intensity, achieved by suspending a high concentration of ultramarine pigment in a synthetic resin. Klein registered IKB as a trademark in 1957, solidifying its place in art history. The color evokes feelings of boundlessness, depth, and the infinite. IKB has since become a symbolic color for art, innovation, and the exploration of the unknown. Its unique spectral properties make it appear exceptionally vibrant and captivating to the human eye. Because the color is unique, it is perfect to build an unique brand identity.

The color #0719ad, also known as International Klein Blue, presents several accessibility considerations for web development. Its deep, saturated hue can pose challenges for users with visual impairments. When used as text, a very light color such as #ffffff or #eeeeee is mandatory to guarantee legibility. Using this color for text, the contrast ratio against a white background should be at least 4.5:1 to meet WCAG AA standards. If used for larger text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Avoid using #0719ad for essential interface elements without careful contrast adjustments. Providing alternative color schemes or allowing users to customize colors can further enhance accessibility. Also avoid using it for focus indicators, ensure focus indicators used with this color are highly visible.
