About International Klein Blue

International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark in 1957. What makes IKB unique is its vibrant intensity and matte finish. The color is achieved through the addition of a synthetic resin binder that suspends the pigment and allows it to retain its pure, unadulterated color impact. It's more than just a color; it's a statement, an artistic concept, and a part of art history. Its usage requires a careful consideration to avoid overwhelming designs and it's most effective when used intentionally to draw attention or create a specific mood.

The color #0226C8, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its very low luminance (brightness) creates insufficient contrast against typical light backgrounds, such as white or very light gray. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is crucial for users with visual impairments, including those with low vision or color blindness. Text rendered in #0226C8 on a white background would likely fail WCAG's contrast ratio requirements, making it difficult or impossible for many users to read. To improve accessibility, it is generally recommended to pair this color with a much lighter color for the background or use it for large graphical elements where contrast is less critical. Consider the needs of all users and use contrast checking tools to ensure compliance.
