International Klein Blue
General Information about International Klein Blue
International Klein Blue, represented by the hexadecimal color code #0A1EC0, is a deep, saturated blue hue known for its intense vibrancy. This color was developed by the French artist Yves Klein in collaboration with a Parisian paint supplier, aiming to capture and preserve the luminosity and depth of pure ultramarine pigment. Klein registered this color as a trademark in 1957. Chemically, the pigment is a synthetic ultramarine, created through a process involving heating clay, sodium carbonate, and sulfur. Its unique visual impact stems from its high concentration of pigment and a special resin medium that allows the color to maintain its brilliance and depth even when dry. It is most often used in modern art pieces.
The hex color #0A1EC0, also known as International Klein Blue, presents significant accessibility challenges. Its deep, saturated hue results in a low luminance value, making it difficult to read text rendered in lighter colors against this background. According to WCAG guidelines, sufficient contrast between foreground and background colors is crucial for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #0A1EC0 often fails to meet these contrast requirements when paired with lighter text colors like white or yellow. Web developers should carefully consider color combinations and utilize contrast checking tools to ensure that content remains accessible. Alternatives include using lighter shades of blue or pairing #0A1EC0 with very dark text colors to improve readability and overall user experience.
