International Klein Blue
General Information
International Klein Blue (IKB), with the hexadecimal color code #0426C6, is a deep, vivid shade of blue that was developed by the French artist Yves Klein. Klein patented the color in 1957 to maintain its unique identity and ensure that it would always be associated with his art. The color is achieved through a specific mixture of ultramarine pigment and a synthetic resin binder, which preserves the pigment's brilliance and intensity. IKB is known for its exceptional purity and depth, which Klein believed conveyed a sense of boundlessness and spiritual transcendence. It became a signature element in his monochromatic paintings and sculptures, contributing to his reputation as a pioneering figure in modern art.
The hex color #0426C6, also known as International Klein Blue, presents several accessibility considerations for web developers. Its high intensity and deep saturation may cause readability issues when used as text color, especially for users with visual impairments. A light color such as white or a very light gray should be used as text color on the dark blue background. To ensure sufficient contrast, aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as specified by WCAG guidelines. This color can be combined with lighter shades of blue or complementary colors to create a visually appealing and accessible design. When using this color for interactive elements like buttons, providing clear visual cues and sufficient hover or focus states is essential. Also avoid using this color as the only way to convey meaning.
