International Klein Blue
About International Klein Blue
The hex color #021C9F, often referred to 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 paint supplier. Klein sought to create a blue that conveyed the purest expression of blue, devoid of any distractions from texture or gloss. IKB is characterized by its matte finish and intense depth, intended to evoke a sense of limitlessness and transcendence. Chemically, IKB is a synthetic ultramarine pigment. The color is not just a hue, but an artistic statement, symbolizing the infinite and the spiritual. It has been used extensively in Klein's monochromatic paintings and sculptures, becoming synonymous with his artistic vision. The color has since become a popular option for those who wish to evoke an emotional connection.
The hex color #021C9F, a deep, saturated blue also known as International Klein Blue, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low luminance, meaning that text or other elements using this color as a background require very light text colors to meet minimum contrast ratios as defined by WCAG (Web Content Accessibility Guidelines). A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure readability for users with visual impairments. When using #021C9F, ensure that text or interactive elements layered on top have a light foreground color (e.g., white or very pale yellow) to achieve sufficient contrast. Without proper contrast, content becomes difficult or impossible to read for individuals with low vision, color blindness, or other visual disabilities. Careful consideration and testing with accessibility evaluation tools are crucial to mitigate these issues and provide an inclusive user experience.

Web Design and Branding
In web design, #021C9F can be used sparingly for accent elements, such as borders, icons, or background highlights, provided that sufficient contrast is maintained with the surrounding content. It can also be used as a primary brand color to evoke feelings of trust, stability, and intelligence. In interior design, #021C9F can serve as a bold accent wall color in modern spaces or as an eye-catching upholstery choice for furniture. When used in fashion, this color makes a statement, often used for evening wear or accessories to add a touch of sophistication. Its rich, intense hue is perfect for creating dramatic and memorable visual effects.
UI/UX Design
International Klein Blue's intensity makes it suitable for highlighting important sections or calls to action, but only if paired with high contrast foreground colors. It's also great for data visualizations in dashboards to create impact. In fashion, this color can be incorporated into textiles to create bold, modern garments. Its association with creativity and innovation makes it a suitable choice for tech companies and artistic brands.
Creative Industries
This color can be used to create bold and creative statements on clothes, as well as to accent certain objects and give a striking contrast. In the world of design, it could be used to highlight a particular part of an object and bring atention to it. In fashion, an outfit in this colour would make the wearer stand out and become the focus of the surrounding crowd.
