International Klein Blue
About International Klein Blue
International Klein Blue, or IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein was fascinated by the intensity of ultramarine and sought to capture the purest, most vibrant expression of blue possible. The color was synthetically created and patented by Klein in 1957 and is registered as IKB 191. IKB's visual impact stems from its high saturation and ability to evoke feelings of depth and boundlessness. It is particularly effective in art because it absorbs light, creating a sense of infinite space. The color is closely associated with Klein's monochrome paintings and sculptures and continues to influence art and design to this day. Because of its unique origins and visual qualities, IKB holds a distinctive place in art history and popular culture.
The hex color #0314B1, also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its dark hue results in very low luminance, meaning it needs to be paired with very light text (such as white or a very pale yellow) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #0314B1 as a background color with darker text would fail these criteria, making content difficult or impossible to read for users with visual impairments. When using this color, careful consideration must be given to contrast and the needs of users with disabilities to ensure an inclusive design.

Applications
Web Design Accent
International Klein Blue can add a touch of sophistication and artistic flair. In website design, it may be used sparingly as an accent color to draw attention to key elements. It is crucial to ensure sufficient contrast with text and other elements to maintain readability and accessibility. It can be incorporated into backgrounds of buttons, headings or other interactive elements to create visual interest.
High Fashion
In fashion, this blue is often seen in high-end garments and accessories. It evokes feelings of confidence, style, and individuality. It is suitable for statement pieces like dresses, scarves, or handbags. Because of its bold and bright nature, it is often paired with neutral colors like white, black, or gray to create a balanced look.
Interior Design Accent
In the realm of interior design, this color makes a bold statement. Use it as an accent wall in a modern living space. Combine it with minimalist furniture and white accents for a sophisticated atmosphere. The key is to balance its intensity with lighter, more neutral shades to prevent the room from feeling overwhelming. It can also be used in artwork or decor to add a pop of color.
