About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0535AE, is a deep and intense shade of blue that is known for its unique visual impact. It was originally developed by the French artist Yves Klein, who sought to create a blue that captured the essence of the sky and the sea. The color is achieved through a specific formulation of ultramarine pigment, which gives it its characteristic vibrancy and depth. International Klein Blue has been used in a wide range of applications, from art and fashion to design and branding, due to its ability to evoke feelings of creativity, sophistication, and modernity. Its distinctive hue has also made it a popular choice for creating eye-catching visual elements and adding a touch of elegance to any project.

The hex color #0535AE, also known as International Klein Blue, presents some accessibility challenges, especially in web design. Its dark hue results in a low contrast ratio when paired with lighter text or backgrounds. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. Therefore, using #0535AE for text requires careful consideration. It is recommended to pair it with very light colors like #FFFFFF to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. When used as a background, lighter foreground elements are essential. Designers should always test color combinations using accessibility tools to ensure readability and usability for all users. Ignoring these accessibility considerations can exclude a significant portion of users.
