About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957, although the trademark's validity has been debated over the years. What makes IKB unique is its ultramarine pigment combined with a synthetic resin binder, which allows the pigment to maintain its brilliance and intensity. The visual impact of IKB is significant, often described as conveying a sense of depth, purity, and infinity. It has been used in various artistic and design applications, from paintings and sculptures to fashion and interior design, maintaining its status as a recognizable and evocative color choice.

The contrast ratio of #0836AC against white is approximately 16.5:1, which exceeds the WCAG AAA standard for text and non-text contrast. This makes it highly accessible for users with visual impairments, including those with low vision or color blindness. When used as a background color, white text would be easily readable. However, its contrast ratio against black is only 1.28:1, which is insufficient for readability. Therefore, using black text on a #0836AC background is not recommended. Designers should prioritize light-colored text or interface elements when using this deep blue to ensure optimal accessibility and usability for all users. Ensure sufficient spacing and sizing of elements for best readability, especially on smaller screens.
