About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0010A8, is a deep, saturated blue hue. It was created by the French artist Yves Klein in collaboration with a Parisian paint dealer. Klein registered this color as a trademark to maintain its unique identity. The color's intense vibrancy stems from its high concentration of ultramarine pigment, which creates a strong visual impact. International Klein Blue is often associated with feelings of depth, infinity, and spirituality. It is used in various art forms, design projects, and even fashion to evoke a sense of awe and wonder.

The color #0010A8, also known as International Klein Blue, presents significant accessibility challenges. Its very dark hue results in extremely low contrast against standard white backgrounds, making text or interactive elements nearly illegible for users with visual impairments. According to WCAG guidelines, this color combination would fail even the strictest Level AAA contrast ratio requirements. To improve accessibility, it's crucial to pair #0010A8 with much lighter colors like whites (#FFFFFF), light yellows (#FFFFE0), or pale blues (#ADD8E6). Using tools to assess color contrast ratios is highly recommended to ensure compliance with accessibility standards, ultimately enhancing the user experience for everyone, including individuals with disabilities. When used for decorative elements, consider adding a high-contrast border for better visibility.
