About International Klein Blue

International Klein Blue (IKB) is a deep blue hue first mixed by the French artist Yves Klein. Klein patented this color in 1957. IKB's visual impact comes from its heavy reliance on ultramarine, as well as Klein's artistic usage of the color. The synthesis of IKB involves suspending the pure ultramarine pigment in a synthetic resin, allowing the pigment to maintain its original qualities and intensity. The color is particularly associated with Klein's monochrome paintings and sculptures. He believed that this particular shade of blue best represented his concepts related to space and spirituality, which he tried to convey through his paintings. It is a vibrant and arresting color that is both memorable and impactful.

The color #0322B0, also known as International Klein Blue, presents significant accessibility challenges, especially in web design. Its very dark hue results in low contrast against similarly dark shades, making it difficult for users with visual impairments to discern text or interactive elements. According to WCAG guidelines, sufficient contrast is crucial for readability. Therefore, when using this color as a background, pairing it with very light text (e.g., white or a very pale yellow) is essential to meet accessibility standards. Tools like contrast checkers can help ensure compliance. Avoid using #0322B0 for critical interactive elements without careful consideration of contrast ratios. Furthermore, ensure that any information conveyed by color alone is also available through other means, such as text labels or icons, to accommodate users with color blindness. Thoughtful application is key to making content inclusive.
