About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein sought to create a blue that best represented his concept of the boundless and immaterial. The color's unique intensity and purity arise from its specific ultramarine pigment and a synthetic resin binder. IKB is not just a color, but an artistic statement, a visual representation of the infinite. It's been used in numerous art installations and is trademarked in France, ensuring its association with Klein's artistic legacy. Beyond its artistic significance, IKB is also studied for its psychological effects, often linked to feelings of calmness and openness.

International Klein Blue (#0623AE) presents unique accessibility considerations for web development. Its high saturation and deep hue can pose challenges for users with visual impairments. When used as a text color, a very light background is essential to provide sufficient contrast, ensuring readability for individuals with low vision. A contrast ratio of at least 4.5:1 is recommended, adhering to WCAG guidelines. Avoid pairing it with similar dark or vibrant colors, as this can lead to eye strain and reduce comprehension. When using it as a background color, ensure that the text is a light and contrasting color. Consider providing alternative color schemes for users who may have difficulty perceiving the color accurately. Furthermore, avoid using this color as the sole indicator for interactive elements, as colorblind users may miss important cues. Supplement color with text labels, icons, or patterns to enhance usability for all users.
