International Klein Blue
About International Klein Blue
International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957, although the trademark's validity is debated. IKB's visual impact comes from its reliance on ultramarine pigment, as well as Klein's artistic use of a matte, synthetic resin binder, which allows the pigment to retain its full intensity and texture. This specific shade of blue is renowned for its intense depth and captivating presence. It's achieved by suspending pure ultramarine pigment in a clear synthetic resin, maintaining the pigment's original qualities and vibrant saturation. The color has been used extensively in art, fashion, and design, recognized for its unique and powerful impact. It represents a specific shade of blue that goes beyond the common blue and is a statement on its own.
The hex color #0019a7, also known as International Klein Blue, presents accessibility challenges due to its low luminance. When used as a background color, it necessitates very light text (white or near-white) 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 to meet AA compliance. Using a color contrast checker is essential to verify compliance. Designers should avoid pairing #0019a7 with mid-tone or dark colors for text or interactive elements. Careful consideration of font size and weight can somewhat mitigate contrast issues, but alternative, lighter shades of blue might provide better accessibility while retaining a similar aesthetic. It's crucial to test designs with users, especially those with visual impairments, to ensure usability. This proactive approach enhances inclusivity and improves the overall user experience.
