General Information about International Klein Blue

#0512AE, also known as International Klein Blue (IKB), is a deep, saturated shade of blue that lies within the ultramarine family. It was created by the French artist Yves Klein, who sought to capture the purest expression of blue, believing it to be the most perfect embodiment of color. Klein registered IKB as a trademark, solidifying its unique place in the art world. The color is created using a synthetic ultramarine pigment, and its intense saturation is achieved by suspending the pigment in a clear, resin-based binder. IKB is known for its ability to evoke feelings of depth, infinity, and transcendence, making it a popular choice for artists seeking to convey a sense of the sublime.

The color #0512AE, a deep, saturated blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of 0.011 makes it difficult to read text rendered in this color against a white or light background. 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. #0512AE fails to meet these criteria against standard light backgrounds. To improve accessibility, consider using this color sparingly for purely decorative elements. When used for text or interactive elements, pair it with very light colors such as white or very light grays to ensure sufficient contrast. Additionally, providing alternative text descriptions for images or graphics using this color can help convey information to screen reader users. Avoid using #0512AE for critical information without careful consideration of contrast to avoid excluding users with low vision or color blindness.
