About International Klein Blue

International Klein Blue, with the hex code #073BA3, is a deep, vivid shade of blue that was first synthesized by the French artist Yves Klein. Klein registered this color as a trademark in 1957, solidifying its status as a unique and iconic hue in the art world. The color is celebrated for its intense saturation and its ability to evoke a sense of depth and immersion. It is achieved through a specific combination of ultramarine pigment suspended in a synthetic resin, which preserves the color's brilliance. It is often associated with concepts of infinity, spirituality, and the boundless nature of the universe. Its distinctive appearance makes it a popular choice for designers and artists seeking to create bold and impactful visual statements. The color's association with Yves Klein's work has also lent it a certain intellectual and artistic cachet.

The hex color #073BA3, also known as International Klein Blue, presents significant accessibility challenges, particularly concerning color contrast. When used as a foreground color against a white or light-colored background, the contrast ratio is insufficient to meet WCAG (Web Content Accessibility Guidelines) standards for Level AA or AAA compliance. This means that users with low vision or color blindness may struggle to read text or distinguish elements using this color. To improve accessibility, it is crucial to pair #073BA3 with a very light color such as #FFFFFF. Alternatively, using #073BA3 for large graphical elements can be acceptable, where the visual distinction doesn't rely solely on color contrast. Designers should always use color contrast checking tools to ensure their color combinations meet accessibility standards, providing a more inclusive experience for all users. It's important to consider that relying solely on color to convey information can exclude users who are unable to perceive those color differences.
