About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #092CAB, is a deep blue hue renowned for its intensity and impact. It was specifically developed by the French artist Yves Klein in collaboration with a paint supplier to achieve a pure, vibrant ultramarine. Klein sought to capture the essence of blue itself, believing it to be the most perfect expression of color. The color is achieved through a unique matte, synthetic resin binder that allows the pigment to maintain its brilliance. It is often associated with concepts of infinity, spirituality, and the sublime, reflecting Klein's artistic vision.

The color #092CAB, also known as International Klein Blue, presents some accessibility challenges. With a low luminance value, it can be difficult to read text rendered in this color against a white background, or vice versa. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. This color may not meet these ratios with lighter backgrounds. To improve accessibility, consider using a lighter tint of this color or pairing it with a very light or very dark color to ensure sufficient contrast. Tools like contrast checkers can assist in evaluating the specific ratios achieved with different color combinations, ensuring readability for users with visual impairments.
