About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0524C5, is a deep and highly saturated shade of blue. This color is renowned for its intensity and depth, and it is named after the French artist Yves Klein, who famously registered the color under his name. Klein used this particular shade extensively in his monochrome paintings and sculptures, seeking to evoke feelings of transcendence and the infinite. The color is achieved through a specific mixture of ultramarine pigment, which gives it its characteristic vibrancy. Its unique visual properties make it stand out from other blues.

The hex color #0524C5, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its very dark hue results in extremely low contrast against standard light backgrounds like white. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive text and other important elements clearly. To ensure accessibility, using #0524C5 for text or interactive elements requires pairing it with a very light color, such as #FFFFFF or a very pale yellow. Even then, careful testing with accessibility evaluation tools is essential to confirm compliance with contrast ratio requirements. Furthermore, avoid using this color as the sole indicator of interactive elements; supplement it with other visual cues like underlines or icons to benefit users with color blindness.
