About International Klein Blue

International Klein Blue (IKB), represented by the hex code #0a2baa, is a deep, vivid blue hue originally conceived by the French artist Yves Klein. Klein patented this specific shade to ensure its exclusive use in his artistic creations, most notably his monochrome paintings and sculptures. IKB is characterized by its intense saturation and matte finish, designed to maximize the visual impact of the color. The color is created to be eye-catching and stand out. It is a specific shade which stands out, partly because of the artists behind it. It is considered as a color that represents creativity and modern art.

The hex color #0a2baa, also known as International Klein Blue, presents some accessibility challenges. Its relatively low luminance value means it may not provide sufficient contrast against light backgrounds, potentially making text or interactive elements difficult for users with visual impairments to perceive. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. To ensure accessibility, consider pairing #0a2baa with very light colors like white (#ffffff) or very light grays for text and interactive elements. Alternatively, using a darker shade of blue or another color altogether might be a better solution for optimal contrast and readability. Tools like contrast checkers can help verify compliance with accessibility standards and ensure content is usable by everyone. Using a slightly lighter shade might improve accessibility.
