International Klein Blue
About International Klein Blue
International Klein Blue (IKB) is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine pigment, combined with a synthetic resin binder that allows the pigment to maintain its color intensity. Yves Klein registered this recipe as a trademark under the name International Klein Blue (IKB) in 1957. The color is known for its remarkable purity and intensity, often described as conveying a sense of depth and boundlessness. This particular shade of blue has become synonymous with Klein's artistic explorations, particularly his monochrome paintings and sculptures. The use of IKB has since extended beyond fine art, influencing fashion, interior design, and popular culture, because it makes people calm and feel safe.
The hex color #002fb2, also known as International Klein Blue (IKB), presents significant accessibility challenges, especially in web design. Its dark hue leads to a low contrast ratio against standard light backgrounds like white (#FFFFFF). This poor contrast makes it difficult for users with visual impairments, such as low vision or color blindness, to read text or distinguish elements displayed in this color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. IKB often fails to meet these standards, potentially excluding a portion of your audience. Therefore, when using IKB, it is essential to pair it with a very light color, ideally white or a very pale yellow, to ensure sufficient contrast. Alternatively, consider using IKB sparingly for decorative elements rather than crucial textual information.

Applications
Modern Art Installations
International Klein Blue is a striking color often used in modern art installations to evoke a sense of depth and boundlessness. Its intense, pure pigment creates a powerful visual impact, drawing viewers into the artwork. The color is typically applied in a uniform, matte finish to maximize its chromatic effect, making it ideal for large-scale canvases and immersive environments. IKB is also used in contemporary fashion for statement pieces, such as dresses and accessories, designed to capture attention and convey sophistication. In interior design, IKB can serve as an accent color in minimalist spaces, adding a touch of drama and intellectual flair, or can be used as an invitation to calm and peace.
Web and UI Design
In web design, IKB can be used strategically for call-to-action buttons or interactive elements to make them stand out. However, careful consideration must be given to its contrast ratio against the background to ensure accessibility. For user interfaces, IKB can be incorporated as a secondary color to highlight important features or sections, providing visual cues to guide users through the application. When integrated thoughtfully, IKB can enhance the aesthetic appeal and user experience of a website or application. Also it can be used as a brand color, because IKB is well know to be the brand color for the arts.
Brand Identity
For brand identity, IKB provides a unique and memorable color, however, brand identity is about more than visual appeal, and it is important to take accessibility into account. If the brand is related to art, IKB may be one of the options, as IKB itself has become part of art history. It's also often used by fashion brands, as it is a very unique and characteristic color. Although very characteristic, it is not recommended for general use because it can cause accessibility issues.
