International Klein Blue
About International Klein Blue
International Klein Blue (IKB), represented by the hexadecimal color code #0728B4, is a deep and vivid shade of blue that was developed and patented by the French artist Yves Klein. This ultramarine blue is renowned for its unique intensity and purity, achieved through a specific mixture of pigment and a synthetic resin binder. Klein sought to capture the essence of the sky and the infinite, and IKB became a defining element of his artistic expression. The color is often associated with spirituality, depth, and a sense of the sublime. It has been widely used in art, fashion, and design to evoke a sense of wonder and contemplation. The color is unique in its matte finish, making it appear intensely saturated.
The hex color #0728b4, also known as International Klein Blue, presents significant accessibility challenges. Its extremely low luminance contrasts poorly with both white and black text, making it difficult to read for users with visual impairments. According to WCAG guidelines, it fails the contrast ratio test for normal text sizes against both white and black backgrounds. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light or dark color to meet minimum contrast requirements. When employing this color, be sure to provide alternative text or visual cues to convey important information, ensuring that all users can access the content effectively. Using a color contrast checker is highly recommended to validate the contrast ratio before deploying the design.

Applications
Web Design Accent Color
International Klein Blue (IKB) can be used as an accent color to bring focus to specific elements, such as buttons, links, or headings. Its vibrant nature makes it ideal for call-to-action elements, drawing the user's eye and encouraging interaction. However, it's essential to use it sparingly and ensure it contrasts well with the background color to maintain readability and avoid visual fatigue. In web design, consider pairing IKB with neutral colors like white, gray, or black to create a balanced and visually appealing layout.
Fashion Design
In the world of fashion, IKB makes a bold statement as a primary color for dresses, suits, or accessories. Its striking hue captures attention and conveys a sense of sophistication and artistic flair. Designers often incorporate IKB in their collections to create eye-catching ensembles that stand out on the runway or in everyday wear. Pair with neutral tones to allow the vibrancy of the IKB color shine.
Interior Design Accent
In interior design, IKB can be used to create a focal point in a room, such as an accent wall or a statement piece of furniture. Its intense hue adds a touch of drama and sophistication to any space, making it ideal for living rooms, bedrooms, or home offices. Alternatively, IKB can be used in smaller doses, such as through decorative pillows, artwork, or rugs, to add a pop of color and personality to a room without overwhelming the space. Complement with neutral walls.
