International Klein Blue
About International Klein Blue
International Klein Blue (IKB), represented by the hex code #0537AE, is a deep, vivid blue hue that was developed and patented by the French artist Yves Klein. Klein sought to capture the purest expression of blue, associating it with the immaterial and the infinite. This color is created using a synthetic ultramarine pigment and a special matte synthetic resin binder, which maintains the color's intensity and luminosity. IKB is known for its remarkable saturation and visual impact, making it a distinctive and recognizable color in art, design, and fashion. It is not only a color but a concept symbolizing boundless space and freedom. The color is now commonly used in branding, design, and digital spaces to evoke a sense of artistic expression and sophistication.
The hex color #0537ae, also known as International Klein Blue, presents some accessibility challenges due to its low luminance. When used as a background color, it requires a very light text color to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Insufficient contrast can make content difficult to read, especially for users with visual impairments. Therefore, it is crucial to carefully choose a foreground color that provides adequate contrast. Tools and online calculators can help determine the contrast ratio between the background and foreground colors to ensure accessibility compliance. Additionally, consider providing alternative color schemes for users who may have difficulty perceiving the intended contrast.
