International Klein Blue
About International Klein Blue
International Klein Blue (IKB), also known as #0511AE, is a deep blue hue first developed by the French artist Yves Klein. It is renowned for its intensity and matte finish, achieved by suspending pure blue pigment in a synthetic resin. Klein registered the color as a trademark in 1957, solidifying its unique identity in the art world. IKB is considered a ultramarine pigment, known for its vivid and captivating appearance. The color evokes feelings of boundlessness and spirituality. It can be seen in various artistic applications, from paintings and sculptures to fashion and interior design. The color is often described as being vibrant and eye-catching. Klein used this blue extensively in his works, seeking to create a visual experience that transcended the physical world.
The hex color #0511ae, also known as International Klein Blue, presents significant accessibility challenges. Its very low luminance (a measure of perceived brightness) results in extremely poor contrast against a white background, failing WCAG (Web Content Accessibility Guidelines) standards for text and non-text contrast. This means that text in this color is likely unreadable for many users, especially those with visual impairments. To improve accessibility, consider pairing this color with very light shades of yellow or gray, or use it sparingly for purely decorative elements. When using this color it is very important to provide sufficient contrast. Tools like contrast checkers can help determine if the contrast ratio meets accessibility guidelines. It is advised not to use this color for important information or interactive elements. If this color is used, a focus indicator for the elements need to be very bright and should stand out from the background and the color itself.

Applications
Web Design Accents
In web design, International Klein Blue can be used as an accent color to draw attention to specific elements, such as call-to-action buttons or headings. Its bold nature makes it effective for creating visual interest, but it should be used sparingly to avoid overwhelming the user. Due to accessibility concerns, it is important to verify that sufficient contrast is provided when it is used in web applications. Also, using the color for backgrounds can bring energy to a design, especially when paired with contrasting colors.
Interior Design Accents
In interior design, International Klein Blue can be used to create a bold and modern statement. An example is using it in a feature wall in a living room or bedroom. It can also be incorporated through decorative items like vases, cushions, or artwork. It is particularly effective in minimalist settings, where it adds a pop of color without overwhelming the space. When the color is combined with white, light grey or beige the room can be lightened up.
Fashion statement
In fashion, this color can be used for clothing items or accessories. A dress or a scarf in this color can make a bold statement. If you want to style this color properly, using light colors can tone down the overall outfit and the color itself. The color can be combined with white sneakers or sandals for a fresh summer look. When the clothes in this color are made of a luxury fabric like silk or satin, they can reflect light in interesting ways.
