About International Klein Blue

International Klein Blue (IKB), with the hex code #0230B2, is a deep, vivid shade of blue that was developed by the French artist Yves Klein. It is known for its striking intensity and matte finish, which enhances its visual impact. Klein sought to create a color that represented the boundless expanse of the sky and the sea, and he patented the process of creating this specific shade of blue. IKB is often associated with concepts of spirituality, infinity, and transcendence. Its unique quality has made it a popular choice in art, design, and fashion, and is known for it's strong appearance and association with Klein's work.

The color #0230B2, also known as International Klein Blue, presents accessibility challenges due to its dark hue. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. It's crucial to test color combinations using accessibility tools to meet these standards. Additionally, avoid using this color for essential UI elements like buttons or links without careful consideration of contrast. For users with visual impairments, the low contrast can make it difficult to distinguish elements, leading to a poor user experience. Using a color contrast checker will help ensure compliance with accessibility standards.
