About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This vibrant color was specifically formulated to visually capture the essence of pure color, aiming to evoke a sense of boundlessness and transcendence. Klein registered this color as a trademark to preserve its unique qualities, and it has since become a symbol of his artistic vision. IKB is achieved through a specific combination of ultramarine pigment with a synthetic resin binder, which allows the pigment to maintain its intensity and visual impact. It is highly regarded for its ability to captivate the viewer and elicit emotional responses, which is why the color is often requested by digital artists as well.

The hex color #032EB1, also known as International Klein Blue, presents several accessibility considerations for web developers. Its high saturation and relatively dark value mean that text rendered in this color requires careful contrast management to be readable, especially for users with visual impairments. According to WCAG guidelines, sufficient contrast ratios must be maintained, typically a minimum of 4.5:1 for normal text and 3:1 for large text. When using #032EB1 as a background color, ensure that foreground text is light enough to meet these contrast standards. Conversely, if used as a text color, the background should be a light hue. Tools for checking color contrast ratios are readily available and should be utilized during the design process. Additionally, consider providing alternative color schemes for users with specific visual needs, enhancing the overall usability and inclusivity of the web application.
