About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0325C7, is a deep and vibrant shade of blue. It is named after the French artist Yves Klein, who patented this specific shade of blue in 1957 for his monochrome paintings. Klein sought to create a color that was as pure and intense as possible, aiming to evoke a sense of boundlessness and spirituality. This color is created by mixing ultramarine pigment with a special resin, which preserves the pigment's intensity and matte finish. It is renowned for its unique depth and visual impact, making it a popular choice in art, design, and fashion. International Klein Blue stands out from other blues due to its unparalleled intensity and ability to captivate the viewer's attention, symbolizing creativity, innovation, and artistic expression.

The hex color #0325C7, also known as International Klein Blue, presents accessibility challenges, particularly in text-based contexts. Its low luminance value of 3 means that it requires careful consideration when pairing it with other colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. When used as a background color, #0325C7 should be paired with a very light text color, such as white (#FFFFFF), to meet these contrast requirements. Tools like contrast checkers can help determine if a specific color combination passes accessibility standards. Additionally, avoid using this color as the sole indicator of interactive elements, such as links or buttons, as color blindness may prevent some users from identifying them. Supplement color cues with text labels or icons to ensure inclusive design.
