International Klein Blue
About International Klein Blue
International Klein Blue, represented by the hexadecimal color code #0018A8, is a deep, vivid shade of blue known for its unique intensity. Developed by the French artist Yves Klein, who patented the color in 1957, it was specifically created to capture and preserve the vibrancy of pure ultramarine pigment. This particular hue is achieved through a specific formula involving a synthetic resin binder that allows the pigment to maintain its brilliance and depth. International Klein Blue is often associated with art, innovation, and sophistication, as well as spirituality. Its striking appearance makes it a popular choice for designers and artists seeking to create a bold and memorable visual impact. The color is composed of 0% red, 9.4% green, and 65.9% blue.
The hex color #0018a8, also known as International Klein Blue, presents significant accessibility challenges. Its low lightness value (approximately 5%) results in very poor contrast against common background colors like white. Consequently, text rendered in #0018a8 on a white background is nearly unreadable for most users, including those with normal vision. Individuals with low vision or color blindness will experience even greater difficulty. To ensure accessibility, it is imperative to avoid using #0018a8 for text or interactive elements without employing a much lighter foreground color to meet WCAG (Web Content Accessibility Guidelines) contrast ratios. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. If #0018a8 is used for decorative purposes, ensuring sufficient contrast isn't as critical, but caution should still be exercised to avoid causing visual strain or obscuring important information. Tools like contrast checkers can help to verify compliance with accessibility standards.

Applications
Website Accent Color
International Klein Blue can serve as an accent color in website design to draw attention to key elements, such as call-to-action buttons or headings. When used sparingly, it evokes a sense of sophistication and creativity. However, due to its poor readability, it's not recommended for large blocks of text. It can be combined with light greys and white to create a modern, minimalist design, or with contrasting colors such as yellow or orange to create a bold, dynamic visual impact. Used carefully, #0018a8 can elevate a website's aesthetic and reinforce brand identity.
Interior Design Accent
In interior design, International Klein Blue can be used to create a focal point in a room. An accent wall painted in this color can add depth and drama to a space. It pairs well with neutral colors like white, gray, and beige, as well as natural materials like wood and stone. Accessories such as throw pillows, vases, or artwork in #0018a8 can also be used to introduce pops of color and create visual interest. This color is often associated with modern and contemporary design styles and can create a sophisticated atmosphere.
Fashion Design
International Klein Blue can be incorporated into fashion design through clothing, accessories, and even footwear. A statement piece in this color, such as a dress or coat, can make a bold fashion statement. It can also be used as an accent color in smaller accessories like scarves, handbags, or jewelry. This color pairs well with neutral tones like black, white, and gray, as well as other bold colors like red or yellow. Because the color expresses authority, strong opinions, and confidence, it is perfect for pieces of clothing like suits or elegant dresses.
