International Klein Blue
About International Klein Blue
International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein sought to create a blue that best expressed his concept of immateriality. The vividness and intensity of IKB come from its reliance on ultramarine pigment and a unique synthetic resin binder that allows the pigment to maintain its brilliance and saturation. IKB is more than just a color; it's a statement, a feeling, an experience. It is visually striking and has an almost mesmerizing quality due to its depth and purity. The color is now trademarked in France in Yves Klein's name.
The hex color #0620BA, also known as International Klein Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text (ideally white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Due to its deep and saturated nature, it should not be paired with dark or similarly intense colors, as this will reduce readability and cause visual strain. When used for interactive elements like buttons, consider providing additional visual cues beyond color alone, such as underlines for links or borders for buttons, to assist users with color vision deficiencies. Proper use of ARIA attributes and semantic HTML can further enhance accessibility.

It's advisable to use this hue sparingly and thoughtfully.
