About International Klein Blue

The hex color code #0326C7 represents a deep, saturated shade of blue, often referred to as International Klein Blue (IKB). This particular hue is known for its intense and captivating quality. IKB was developed by the artist Yves Klein, who sought to create a blue that was as pure and vibrant as possible. The color is achieved by suspending ultramarine pigment in a synthetic resin, which preserves the pigment's brilliance. It is a very dark color, which makes it useful as an accent color in creative applications. The color is not safe for use with text, since it is too dark and lacks contrast.

The hex color #0326C7, also known as International Klein Blue, presents significant accessibility challenges. Its very dark hue results in extremely low contrast against standard white backgrounds, failing WCAG (Web Content Accessibility Guidelines) standards for text and non-text contrast. This color should not be used for text, icons, or important graphical elements without careful consideration. When using this color it is important to provide sufficient contrast, for example by using a very light color for text on a background with the color #0326C7. If you want to use this color in your design, consider using different shades of the color to find an accessible combination.
