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. Klein patented this color to maintain its unique identity and prevent its widespread reproduction. The color is renowned for its striking intensity and velvety matte appearance, which Klein achieved by suspending pure blue pigment in a synthetic resin. He believed that this color captured the purest expression of blue, unadulterated by gloss or texture. IKB has since become a symbol of artistic innovation and avant-garde aesthetics, frequently used in various creative fields beyond painting, including fashion, graphic design, and interior decoration.
The hex color #0118B3, also known as International Klein Blue, presents significant accessibility challenges due to its very low luminance value. Its contrast ratio against a white background is extremely poor, making text or interactive elements using this color difficult to read for individuals with visual impairments. To ensure inclusivity, it is strongly recommended to avoid using #0118B3 for text, icons, or essential user interface components on light backgrounds. When using this color, pair it with very light shades, such as white or light yellows to meet WCAG (Web Content Accessibility Guidelines) requirements for contrast. Also, consider providing alternative high-contrast themes or color options to enhance accessibility for all users. Avoid using it as the only indicator as it can lead to bad UX for color blind people.

Applications
Web Design Accent
In web design, International Klein Blue can be used as an accent color to draw attention to specific elements without overwhelming the user interface. It's suitable for highlighting buttons, links, or important notifications when paired with a contrasting background color. However, it should be avoided for extensive text blocks due to readability issues. In digital art, this color can create vibrant and captivating visuals, particularly when combined with complementary hues. Use sparingly to maintain readability and a positive user experience.
Art and Fashion
International Klein Blue is widely used in fine art and fashion to create bold and striking statements. Its unique intensity makes it ideal for paintings, sculptures, and clothing items intended to stand out. In interior design, this color can be used as an accent wall or in decorative elements to add a touch of sophistication and drama to a space. Consider using this color for accessories like vases and pillows. Balance it with neutral colors like white, grey, or beige to create a harmonious and visually appealing environment.
Data visualization
This color can be used in data visualization to represent different categories or highlight trends. However, caution is advised, especially when presenting information to a broad audience, as its low contrast could make it difficult for some viewers to interpret the data. To ensure clarity, use International Klein Blue in conjunction with clear labels and avoid using it for small details. When used, implement in large backgrounds and ensure enough contrast with foreground components
