About International Klein Blue

International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. This particular shade is renowned for its vivid intensity and remarkable purity, achieved through the careful suspension of pigment in a synthetic resin. Klein registered this color as a trademark to maintain its unique identity. Its captivating quality stems from its ability to evoke feelings of infinity, depth, and the ethereal. Its use extends beyond the art world, permeating various creative domains, including fashion, graphic design, and interior decorating, where it continues to captivate and inspire.

The hex color #0317B1, also known as International Klein Blue, presents significant accessibility challenges, particularly concerning color contrast. When used as a background, text needs to be very light to ensure readability. A light shade of yellow or white is typically necessary to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Otherwise, users with low vision or color blindness may struggle to perceive content clearly. It's crucial to avoid pairing it with darker colors like black or dark grays, as this would exacerbate readability issues. In design, careful attention must be given to the size and weight of text rendered against this background to further mitigate potential accessibility barriers. Using tools for checking color contrast during the design phase will help ensure compliance with accessibility standards and inclusive user experience.
