International Klein Blue
About International Klein Blue
International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade was developed as part of Klein's exploration of color as a vehicle for conveying pure idea. IKB's brilliance and intensity are achieved through a unique formulation that includes a synthetic resin binder, which allows the pigment to retain its vibrancy. In the RGB color model, International Klein Blue is composed of approximately 2% red, 13% green, and 69% blue. Its hex code is #0522AF. The color is notable for its matte finish, which enhances its depth and intensity. Klein used IKB extensively in his monochrome paintings and sculptures. He even patented the color to protect its unique properties and ensure its consistent use. The color is considered a symbol of modernity and innovation.
The color #0522AF, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its dark hue results in very low contrast against typical light backgrounds like white (#FFFFFF). This low contrast can make text and other elements difficult to read for users, particularly those with visual impairments or color blindness. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability. For normal text (14pt and above), a contrast ratio of 4.5:1 is recommended, while for large text (18pt and above), a ratio of 3:1 is required. International Klein Blue often falls far short of these standards, necessitating careful consideration of foreground colors. To improve accessibility, consider using lighter text colors such as white or very light grays. Tools that check color contrast ratios can be invaluable in determining whether a color combination meets accessibility standards. Also, avoid using this color for essential interactive elements, as those elements should have sufficient contrast to indicate their purpose.

However, in web design, it should be used sparingly and strategically to avoid overwhelming users or creating accessibility issues. It can be effective for highlighting key elements or creating visual interest, but should always be paired with accessible foreground colors.
