About International Klein Blue

International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This specific shade of blue was developed by tinting ultramarine with a synthetic resin, and it's renowned for its visual impact and unique matte appearance. Klein registered this color as a trademark to preserve its distinctiveness. In the hexadecimal color system, IKB is represented as #0828AC. This color evokes feelings of depth, creativity, and tranquility. It is often associated with art, spirituality, and innovation, and has been used in various artistic and commercial contexts to represent these concepts. The color stands out due to its strong saturation and matte finish, creating a captivating and immersive visual experience.

The hex color #0828ac, also known as International Klein Blue, presents some accessibility challenges, especially when used as a background color for text. Its dark nature means that it requires a very light foreground color to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as specified by WCAG guidelines. Using online contrast checkers is crucial to verify that the chosen foreground color meets these standards. Additionally, avoid using this color for essential interactive elements without clear visual cues, as color blindness can affect perception. Provide alternative visual cues, such as underlines or icons, to ensure usability for all users. When used for decorative purposes, accessibility considerations are less critical but still relevant to overall user experience.
