About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep shade of blue that was developed by the French artist Yves Klein. Its unique characteristic lies in its remarkable intensity and purity, achieved through a specific paint formula that suspends ultramarine pigment in a synthetic resin. Klein registered this color under patent, solidifying its identity. The color embodies Klein's artistic vision of capturing the immateriality and boundless nature of the sky and sea. IKB has since become an iconic color in art, design, and fashion, known for its ability to evoke a sense of depth, spirituality, and visual impact. It is a testament to the power of color in expressing artistic concepts and cultural identity.

The hex color #0235B2, also known as International Klein Blue, presents specific accessibility considerations for web developers. Due to its deep, saturated hue and low luminance, it can pose challenges in terms of contrast. When used as a foreground color for text, it requires a light background to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. Using a color contrast checker is crucial to verify compliance. Avoid pairing #0235B2 with other dark or similarly saturated colors, as this can lead to visual strain and reduced comprehension for users, especially those with visual impairments. Thoughtful application of this striking color is essential to maintain an inclusive and accessible design.
