About International Klein Blue

International Klein Blue, also known as IKB, is a deep shade of blue first mixed by the French artist Yves Klein. Klein created this vivid hue as part of his quest to capture the purest expression of blue, aiming for a color that embodied his concept of limitless space and spiritual depth. IKB is characterized by its rich, matte finish, achieved through the use of a special synthetic resin that preserves the pigment's intensity. The color was officially patented by Klein in 1957, solidifying its place in art history. Its intense saturation makes it visually striking and has led to its adoption in various fields beyond art, including fashion, design, and even branding. It is often associated with depth, clarity, and a sense of the infinite, making it a powerful and evocative color choice.

The color #022AB2, a deep shade of blue also known as International Klein Blue, presents some accessibility challenges, particularly regarding contrast. When used for text, it's crucial to pair it with a very light color like white or a pale yellow to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. Using online contrast checkers is highly recommended to verify the compliance of color combinations. Furthermore, avoid using this color as the sole means to convey important information; supplement it with text labels or icons. In terms of usability, consider that prolonged exposure to highly saturated blues can sometimes cause eye strain, so it is best used sparingly in user interfaces.
