International Klein Blue
About International Klein Blue
International Klein Blue, often abbreviated as IKB, is a deep blue hue first mixed by the French artist Yves Klein. The color's visual impact comes from its heavy reliance on ultramarine, as well as Klein's matte, synthetic resin binder that suspends the color pigment and allows the pigment to maintain its original qualities. Klein patented IKB in 1957, although he always maintained that this wasn't done to restrict other artists from using the color, but rather to retain the color's integrity. IKB is often associated with a sense of depth, transcendence, and the infinite. It is an intense and captivating color that has been used in various artistic and design applications.
The hex color #0115B3, a deep shade of blue, presents accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 1.2% necessitates careful consideration of color contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. When using #0115B3 for text, it's crucial to pair it with a very light color, such as white or a pale yellow, to ensure readability. For graphical elements and user interface components, a contrast ratio of at least 3:1 is required. Avoid using this color for essential visual information without sufficient contrast, as it may be imperceptible to some users. Tools like contrast checkers can assist in evaluating color pairings.

Applications
Web Design
In web design, International Klein Blue can be used to create a sense of depth and sophistication. However, due to its low luminance, it should be used sparingly, perhaps as an accent color or for decorative elements rather than for large blocks of text or critical interface components. Consider using it for headings or calls to action, paired with a very light background to ensure readability and accessibility. Its bold nature can also be leveraged for branding elements to convey innovation.
Fashion
In fashion, International Klein Blue can make a bold statement. Use it for clothing, accessories, or as an accent color in an outfit. Pair it with neutral colors like white, gray, or black to create a striking contrast, or combine it with complementary colors for a vibrant look. Its intense hue can also be used in makeup, such as eyeshadow or eyeliner, to add a pop of color to the face. It is suitable for modern and avant-garde styles.
Interior Design
For interior design, using International Klein Blue as an accent wall can create a captivating focal point. It works particularly well in modern and minimalist spaces. Balance its intensity with neutral colors such as white, gray, or light wood tones to prevent the room from feeling too overwhelming. Consider using it in smaller doses, such as for throw pillows, artwork, or decorative objects, to add a pop of color without dominating the entire space.
