General Information about International Klein Blue

International Klein Blue, represented by the hex code #0835AC, is a deep, vivid shade of blue that is known for its intense and captivating presence. It was famously created by the French artist Yves Klein in collaboration with a Parisian paint dealer, and it became the signature color of his monochrome paintings. Klein registered the color as a trademark in 1957. Chemically, the pigment used to create IKB is a synthetic ultramarine blue, which is characterized by its exceptional purity and brightness. The color is often associated with concepts such as infinity, spirituality, and the sublime, reflecting Klein's artistic vision. In the realm of color theory, IKB stands out as a unique and recognizable hue that has influenced art, design, and popular culture.

The hex color #0835AC, also known as International Klein Blue, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it requires very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given the darkness of #0835AC, standard dark text will almost certainly fail these contrast checks. Therefore, pairing it with colors like white (#FFFFFF) or very light shades of yellow or gray is advisable. Also, avoid using this color for interactive elements unless sufficient visual cues, such as borders or icons, are provided alongside color changes. Users with visual impairments, such as low vision or color blindness, may struggle to distinguish elements if color is the only differentiator. Always prioritize clear and high-contrast text and interactive elements to ensure an inclusive user experience.
