International Klein Blue
About International Klein Blue
International Klein Blue, often referred to as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Klein sought to create a blue that best represented his concepts of immateriality and transcendence. The color is achieved by mixing ultramarine pigment with a synthetic resin binder, which allows the pigment to maintain its intensity and vibrancy. IKB is more than just a color; it's a statement. It’s a registered trademark under the name International Klein Blue (IKB) and has found its way into various artistic and design applications due to its unique saturation and visual impact.
The color #0317B0, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of 0.004 makes it difficult to perceive against typical light backgrounds. According to WCAG guidelines, it fails the contrast ratio test against white (#FFFFFF) for normal text (4.5:1) and large text (3:1). To ensure accessibility, this color should be paired with very light colors like white or very pale yellows for sufficient contrast. Avoid using it for critical information or interactive elements without careful consideration of contrast. Using tools to check color contrast ratios is highly recommended to ensure compliance with accessibility standards and provide a usable experience for all users. Text using this color requires careful consideration.

Fashion Accents
In the realm of fashion, International Klein Blue serves as a striking accent color. A scarf, a handbag, or a pair of shoes in this vibrant hue can elevate any outfit, adding a touch of boldness and refinement. Its versatility allows it to complement a wide array of styles, from casual to formal. When styling, consider color blocking with complementary or contrasting colors to create a dynamic and eye-catching ensemble. This color is often used in clothing like dresses or shirts.
Interior Design Accent Walls
This deep blue is perfect for creating a dramatic and sophisticated backdrop in interior design. Imagine a feature wall in a living room or bedroom painted in this color. It can create a calming, yet vibrant atmosphere, especially when paired with neutral-toned furniture and accents. However, ensure the room has ample lighting to prevent it from feeling too dark or closed in. Consider using it sparingly in smaller spaces to avoid overwhelming the area. It is often paired with white or grey.
