International Klein Blue
About International Klein Blue
The color #0227C1, also known as International Klein Blue (IKB), is a deep and highly saturated shade of blue. It was developed by the French artist Yves Klein in collaboration with a Parisian paint dealer, Edouard Adam, to capture the essence and intensity of ultramarine pigment. Klein patented the color in 1957, ensuring its unique status within the art world. This specific hue is notable for its vividness and the feeling of depth it evokes. Its intense saturation is designed to convey a sense of pure color, detached from any representational or decorative function. IKB has been widely used in Klein's monochrome paintings and sculptures, becoming a signature element of his artistic expression.
The hex color #0227C1, representing International Klein Blue, presents significant accessibility challenges, especially in web design. Its extremely low luminance value results in very poor contrast against common background colors like white. Text using this color would be nearly unreadable for most users, and especially problematic for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color falls far short of meeting these recommendations when paired with light backgrounds. Therefore, it's essential to use this color sparingly and thoughtfully. When used, ensure a high contrast ratio by pairing it with a very light color, ideally white or a very pale yellow. Also, do not rely on color alone to convey important information. Always provide alternative cues such as text labels or icons to ensure accessibility for all users.

Applications
Website Accent Color
International Klein Blue is a powerful color choice for website accents, particularly in minimalist designs where a single, bold color is used to draw attention to key elements like call-to-action buttons or important links. Its intensity can create a sense of urgency and importance, making it effective for guiding users through a specific flow. However, due to its low luminosity, it should be used sparingly and carefully, ensuring sufficient contrast with surrounding elements for readability and accessibility. When combined with clean typography and ample white space, IKB can create a memorable and impactful user experience.
Fashion Accent
In the realm of fashion, this intense blue can be used to create striking statement pieces. Imagine a silk scarf, a bold blazer, or uniquely designed jewelry in this shade. To avoid overwhelming the outfit, balance it with neutral colors like white, black, or grey. Smaller accessories can add a pop of color without being too overpowering. Use it in makeup, such as eyeliner, for a bold, modern look. Keep in mind that because it’s a highly saturated color, it’s best to use it as a feature and not as the foundation of the outfit.
Interior Design Accent
This hex color can make a huge statement as an accent wall in an interior design. It can give the room a touch of artistic and modern feel. It's a bold choice, so it's best used in rooms with lots of natural light and with neutral or very light colored furniture to balance out the intensity. It can work well in home offices or studios to inspire creativity. Alternatively, use the color in smaller doses, such as cushions, artwork, or vases. When the room has a neutral base, it provides a striking focal point, or it can become a conversation starter.
