General Information about International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade was developed as part of Klein's search for a color that possessed the greatest intensity of expression. Klein sought a blue that would represent the immateriality and spirituality he was exploring in his art. Chemically, IKB is a synthetic ultramarine pigment. The vividness and intensity of IKB stem from its unique formulation, where the pigment is suspended in a clear synthetic resin, allowing for maximum saturation and luminosity. Because of the unique color and saturation, it's a often used color in modern art.

The color #0628AE, International Klein Blue, presents some accessibility challenges. Its dark hue means it generally requires light-colored text for sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #0628AE for backgrounds, ensure your text meets these contrast requirements to accommodate users with visual impairments. Tools like contrast checkers can help determine if your color combinations are accessible. Also, avoid relying solely on color to convey important information; use text labels or other visual cues as well. For interactive elements like buttons, provide clear visual feedback on hover or focus to enhance usability for all users.
