International Klein Blue
About International Klein Blue
International Klein Blue, represented by the hex code #0437b0, is a deep, vibrant shade of blue that is closely associated with the French artist Yves Klein, who patented the color in 1957. This particular hue is renowned for its intensity and matte finish, which Klein believed enhanced its emotional impact. Chemically, it's a specific formulation of ultramarine pigment. In the RGB color model, it is composed of 1.6% red, 21.6% green, and 69% blue. It is perceived as a cool and intellectual color. It conveys a sense of depth and infinity, and the lack of reflective highlights makes it appear almost velvety. Klein chose this color to represent the boundless nature of imagination and spirituality.
The hex color #0437b0, also known as International Klein Blue, presents accessibility challenges due to its low luminance. When used as text on a white background, it fails to meet WCAG (Web Content Accessibility Guidelines) AA and AAA standards for contrast ratio. This means that users with visual impairments may struggle to read the text comfortably. To improve accessibility, consider using #0437b0 for larger text elements, decorative elements, or backgrounds paired with lighter text. Alternatively, using a much lighter color such as a light gray or even a very pale yellow can provide sufficient contrast. Always test color combinations with accessibility checkers to ensure compliance with accessibility standards and provide an inclusive user experience for everyone, including those with low vision or color blindness. Ensure sufficient contrast to improve the readability and overall usability of your design.
