About International Klein Blue

International Klein Blue, represented by the hex code #0a24aa, is a deep, saturated shade of blue renowned for its captivating intensity. It was specifically developed by the French artist Yves Klein in the 1950s as a medium for expressing his artistic vision. Klein sought to capture the purest, most evocative form of blue, unburdened by surface reflections. The color is achieved through a specific formulation of ultramarine pigment suspended in a synthetic resin, maintaining its vibrancy. Its unique chromatic presence has made it iconic and associated with both modern art and intellectual depth. The color's distinct appeal makes it a prominent element in a variety of applications.

The hex color #0a24aa, also known as International Klein Blue, presents several accessibility considerations for web developers. Its high saturation and relatively dark tone result in a low luminance value. Consequently, using #0a24aa as a background color necessitates pairing it with a very light text color to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, as per WCAG guidelines, while a ratio of 3:1 is acceptable for large text. Avoid using this color for crucial interactive elements or text if adequate contrast cannot be achieved. When using this color, providing alternative visual cues, such as underlines or icons, in addition to color, can improve accessibility for users with color vision deficiencies. Careful consideration of color combinations is essential to ensure an inclusive user experience.
