About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine, as well as Klein's matte, synthetic resin binder that allows the pigment to maintain its brilliance. Klein patented this process shortly before his death. The color is visually stunning and evokes a sense of depth and intensity. It is often associated with creativity, spirituality, and the infinite. Its distinctive appearance makes it a favorite among artists and designers who want to create memorable and impactful designs.

International Klein Blue (#0024C2) offers moderate contrast against white, but careful consideration is needed for text. WCAG guidelines suggest a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using this blue for text on a white background may not meet these guidelines for normal text sizes, potentially causing readability issues for users, especially those with visual impairments. Therefore, it's crucial to use a color contrast checker to ensure compliance. Consider using a lighter text color like white or a very light gray on this dark blue background, or a much darker text color like black or a very dark grey on a lighter background of this blue to achieve sufficient contrast. Adjusting font weight can also improve readability. Always prioritize accessibility to ensure inclusivity.
