International Klein Blue
About International Klein Blue
International Klein Blue, represented by the hex code #0729ad, is a deep, vibrant shade of blue that was developed by the French artist Yves Klein. Klein patented this color in 1957 to ensure its unique identity and use in his artworks. The color is known for its intense saturation and ultramarine hue, which is achieved through a specific mixture of ultramarine pigment and a synthetic resin binder. It's often described as a pure expression of blue, evoking feelings of depth, spirituality, and infinity. In the RGB color model, it is composed of 2.75% red, 16.08% green, and 67.84% blue. Its distinctive characteristics make it popular in the art world. In web design, due to its intensity, it is usually used as an accent color or in smaller doses to draw attention.
The hex color #0729ad, also known as International Klein Blue, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it requires very light text (ideally white or near-white) to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Conversely, as a text color, it needs a very light background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. Tools like WebAIM's Contrast Checker can be used to assess the contrast ratio between #0729ad and other colors. Due to its low luminance, this color is not suitable for situations where color alone is used to convey critical information. Providing additional visual cues, like icons or text labels, is crucial to avoid accessibility issues. The dark nature of the color can be problematic for users with light sensitivity, therefore, it is important to use it sparingly.
