International Klein Blue
About International Klein Blue
International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. The visual impact of IKB comes from its heavy reliance on ultramarine pigment, as well as Klein's artistic use of a matte, synthetic resin binder, which suspends the color pigment and allows the pigment to retain its original qualities. The hue is a vivid shade of blue that appears to 'glow' and has become iconic in the art world. It represents the immateriality and boundlessness that Klein sought to express in his artistic creations. Its captivation also comes from its strong chromaticity, which brings the color close to the edge of human blue vision.
The color #0A32AA, also known as International Klein Blue, presents certain accessibility challenges, particularly when used as text against a white background. Its low luminance value (relative to white) can result in insufficient contrast, making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #0A32AA often falls short of these recommendations when paired with light backgrounds. To improve accessibility, consider using #0A32AA sparingly for large headings or graphic elements, or pairing it with a very light color that provides sufficient contrast, such as white or a very pale yellow. Additionally, it's crucial to test color combinations with accessibility evaluation tools to ensure compliance with accessibility standards and provide an inclusive user experience. Using this color as background color requires white or very light text colors.

Consider pairing it with neutral colors like gray, white, or black to balance its intensity.

Web design highlight color
In web design, the color is suitable as a highlight color. This can be for highlighting buttons or links or as an attention grabbing color to point to important messages. It can also be used as a background color for a banner. For that purpose, white or very light colors should be used as the text color.
