About International Klein Blue

International Klein Blue, represented by the hex code #0020B4, is a deep, intense blue hue that was originally created by the French artist Yves Klein. Klein patented the color in 1957 to ensure its preservation and maintain its unique visual impact. It's known for its matte finish, which enhances its vibrancy and depth. The color is achieved through a specific combination of ultramarine pigment, combined with a synthetic resin binder. The intention of Yves Klein in the creation of this color was to reproduce with the highest fidelity the visual perception of pure ultramarine pigment. It is a color often associated with art, creativity, and innovation, and remains a prominent choice for designers and artists seeking to evoke a sense of depth and visual impact.

The hex color #0020B4, also known as International Klein Blue, presents some accessibility challenges, particularly in web design. Due to its dark hue and relatively low luminance, it requires careful consideration to ensure sufficient contrast with foreground text or elements. According to WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #0020B4 as a background, it's crucial to pair it with light-colored text (e.g., white or a very pale yellow) to meet these contrast requirements. Tools like contrast checkers can help verify compliance. Additionally, consider users with visual impairments; avoid using this color alone to convey critical information. Supplement color-coding with text labels or icons to ensure inclusivity and usability. Using this specific hue might exclude users with extreme light sensitivity.
