About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Its striking ultramarine shade, achieved through a unique binder, is registered as a trademark. This color is renowned for its intense saturation and the emotional response it evokes. Klein used this color extensively in his monochrome paintings and sculptures, aiming to create a feeling of limitless space and depth. IKB is more than just a color, it's an artistic statement that represents abstraction and the infinite. It is a memorable color and often associated with the avant-garde movement.

International Klein Blue (#0632AE) presents some accessibility challenges, especially when used for text or interactive elements. Its dark hue results in a low contrast ratio against light backgrounds, potentially making it difficult for users with visual impairments to read or distinguish content. To ensure accessibility, it is crucial to pair it with very light colors such as white or a very pale yellow for text, achieving a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines. Using it for purely decorative purposes is fine, but avoid using it as a primary indicator of any UI-element. When using it for backgrounds, ensure that all elements on top of it have sufficient contrast and are easily distinguishable. Consider providing alternative high-contrast themes or options for users with visual impairments to customize the color scheme to their needs.
