About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #061DA6, is a deep, vivid blue hue known for its intense saturation. It was developed by the French artist Yves Klein in collaboration with a Parisian paint supplier, and patented in 1957. Klein sought to create a blue that captured the purest expression of the color, embodying a sense of limitless space and spirituality. The color is achieved through a specific formula that maximizes the pigment's intensity while retaining its visual impact. International Klein Blue has since become iconic in the art world, symbolizing innovation, depth, and the pursuit of the infinite. It has transcended its origins, influencing various fields including design, fashion, and popular culture.

The hex color #061DA6, also known as International Klein Blue, presents significant accessibility challenges. Its low luminance value necessitates careful consideration of color contrast, particularly when used for text or interactive elements. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. For text, a contrast ratio of at least 4.5:1 against its background is recommended for normal text and 3:1 for large text. Given the darkness of #061DA6, pairing it with very light colors like #FFFFFF (white) or very light grays is essential to meet these standards. Using color contrast checkers is highly advised to ensure compliance. Avoid using this color for critical information without ensuring adequate contrast, as it can be illegible for many users, leading to a poor user experience. Also avoid using it for small icons or detailed graphics.
