International Klein Blue
About International Klein Blue
The hexadecimal color #071AAD, often referred to as International Klein Blue, is a deep and intense shade of blue. It is characterized by its high saturation and relatively low lightness value. This color is created by combining small amounts of red (07) and green (1A) with a significant amount of blue (AD) in the RGB color model. In the CMYK color model, it would have a high percentage of cyan, magenta, and black, with little to no yellow. This color is associated with feelings of tranquility, depth, and authority. It can evoke a sense of trust and stability, but also a feeling of coldness or distance if overused. The color is named after the French artist Yves Klein.
The hex color #071AAD, a deep, saturated blue reminiscent of International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low lightness value (YIQ around 10) means that text rendered in this color requires a very light, high-contrast background to be legible. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #071AAD for text on a white background would fall far short of these recommendations, potentially excluding users with low vision or color blindness. Designers should carefully consider the context in which this color is used and provide alternative, higher-contrast color combinations to ensure content is accessible to all users. Tools like contrast checkers can help evaluate the compliance of color pairings.

Applications
Corporate Website Design
In web design, this color can be used to create a sense of trust and authority. For example, it can be applied to the header or sidebar of a financial institution's website. However, due to its low luminance, it's crucial to pair it with a light color like white or a very pale yellow for text and interactive elements to ensure readability and accessibility. It can also be used sparingly for call-to-action buttons to make them stand out, but always ensure sufficient contrast.
Interior Design Accent
In interior design, International Klein Blue can be used as an accent color to add a pop of color to a room. It works well with neutral colors like white, gray, and beige. A single piece of furniture, such as a chair or a lamp, in this color can make a bold statement. However, using too much of this intense blue can be overwhelming, so it's best to use it sparingly and strategically to create a visually appealing and balanced space.
Fashion Design
In fashion, this color can be used to create a bold and sophisticated look. A dress or suit in this color can make a strong statement. Accessories like handbags or scarves in this color can add a pop of color to a neutral outfit. Pair it with complementary colors like orange or yellow for a vibrant look, or with neutrals like black or white for a more classic and elegant style.
