General Information about International Klein Blue (#093AAB)

International Klein Blue, represented by the hexadecimal color code #093AAB, is a deep and vivid shade of blue known for its intense saturation and visual impact. It was originally created by the French artist Yves Klein in collaboration with a Parisian paint dealer, and patented in 1957. The color's unique quality stems from its matte finish, which enhances its depth and allows it to absorb light, creating a captivating and immersive visual experience. IKB has become synonymous with Klein's artistic vision and has been widely adopted in various fields, including art, design, and fashion, for its striking and memorable aesthetic.

The hex color #093AAB, also known as International Klein Blue, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color, it requires careful consideration of the background color to ensure sufficient contrast for readability. A light background is highly recommended to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios, specifically aiming for a ratio of at least 4.5:1 for normal text and 3:1 for large text. Designers should avoid pairing #093AAB with dark or similarly saturated colors, as this can result in poor readability and visual strain for users, especially those with visual impairments. Tools like contrast checkers can be used to verify the color combination's compliance with accessibility standards, ensuring an inclusive and user-friendly experience for all users.
