International Klein Blue
About International Klein Blue
International Klein Blue (IKB), also known as #021DB2, is a deep blue hue first mixed by the French artist Yves Klein. Klein registered this color as a trademark. IKB's visual impact comes from its heavy reliance on ultramarine pigment, as well as Klein's artistic vision. The color is known for its intensity and purity, setting it apart from other blues. IKB has found use in many creative fields due to its captivating qualities, and also has an interesting history and an established place in colour and design theory. IKB is known to be used in the arts, and also in design, fashion, and even scientific research. It is an ultramarine pigment.
The color #021DB2, a deep blue, presents significant accessibility challenges. Its low luminance contrasts poorly with both white and black text, making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color is unlikely to meet these standards when paired with typical background colors. To improve accessibility, consider using lighter shades of blue or pairing it with high-contrast colors like white or yellow for graphical elements only. Ensure text using this color has a sufficient contrast ratio. Providing alternative color schemes will significantly benefit users with color blindness or other visual impairments. Testing with accessibility tools is crucial.

Applications
Web Design Accents
International Klein Blue, while striking, can be used sparingly in web design to draw attention to specific elements like call-to-action buttons or headings. Due to its intensity, it's best suited for accents rather than large areas or text. In user interfaces, it might be applied as a highlight color or for interactive elements to guide the user's eye and signify importance. It is crucial to test accessibility to ensure readability for all users.
Fashion and Beauty Statements
In the realm of fashion and beauty, International Klein Blue is a bold choice. It can be used in makeup as an eyeshadow or eyeliner to make a strong statement. In fashion, a single garment or accessory in this hue can transform an entire outfit, such as a dress or shoes. However, it's essential to balance this intense color with neutral tones to avoid overwhelming the overall aesthetic and make the look more versatile and accessible.
Interior design accents
This vivid blue can act as an accent color in interior design. A single wall, a piece of art, or decorative pillows could all use this colour. Balance is very important when using this colour in large rooms. To make it look good, use natural colours and materials such as wood, to make it an eyecatcher.
