About International Klein Blue

The hex color #0816AC, also known as International Klein Blue (IKB), is a deep and intense shade of blue. It is a proprietary color developed by the French artist Yves Klein. Klein sought to capture the purest expression of blue, aiming to evoke feelings of boundlessness, spirituality, and transcendence. The color's unique matte finish enhances its depth and intensity, setting it apart from other blue hues. IKB is not just a color; it is a statement—a visual representation of the infinite and the immaterial. Its formulation involves a synthetic ultramarine pigment suspended in a clear resin, allowing the pigment to retain its brilliance. This ensures its vibrancy and allows for a more profound visual impact.

The color #0816AC, a deep, vibrant blue, presents several accessibility considerations for web development. When used as a background color, sufficient contrast with foreground text is crucial. A light-colored text, such as white or a pale yellow, is recommended to ensure readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios (minimum 4.5:1 for normal text and 3:1 for large text). Avoid pairing it with darker colors or those with similar luminance, as this can cause visual strain. Additionally, consider providing alternative visual cues, such as icons or borders, for users with color vision deficiencies. When used for interactive elements like buttons or links, hover and focus states should have distinct visual changes to aid users who navigate with keyboards or screen readers. Careful attention to these details ensures inclusivity and a positive user experience for individuals with diverse visual abilities.
