About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #061DAE, is a deep and intense shade of blue that holds a significant place in art history. It was developed by the French artist Yves Klein in collaboration with a Parisian paint supplier, E. Adam, specifically for his monochrome paintings. The unique quality of IKB lies in its ultramarine pigment, which retains its brilliance and intensity because it is suspended in a clear synthetic resin, allowing the pigment to maintain its original depth and luminosity. This striking blue has become synonymous with Klein's artistic vision, representing boundless space and infinite possibilities. Its visual impact is both captivating and evocative, making it a distinctive and recognizable color in the art world.

The hex color #061DAE, representing International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely dark shade results in very low contrast against white backgrounds, making text and interactive elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are essential for ensuring readability and usability. To improve accessibility, it is crucial to pair this color with very light hues, such as white or very pale yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using this color for critical interactive elements without clear visual cues, as users may struggle to identify them. Providing alternative color schemes or allowing users to customize colors can further enhance the accessibility of designs incorporating this deep blue.
