About International Klein Blue

International Klein Blue, represented by the hex code #0325ba, is a deep and intense shade of blue that was developed by the French artist Yves Klein. He sought to create a blue that was as pure and evocative as possible, encapsulating the vastness of the sky and the depth of the sea. This particular blue is a vibrant ultramarine, leaning towards a slightly violet undertone. Its formulation is specifically a matte version of ultramarine, achieved by suspending the pigment in a synthetic resin. Klein famously registered this color as a trademark, solidifying its place in art history. It is often associated with concepts of freedom, transcendence, and the infinite. Its unique visual impact makes it a memorable and striking color choice. The color is often associated with art and elegance.

The hex color #0325ba, also known as International Klein Blue, presents some accessibility challenges due to its deep, saturated hue. When used as a background color, it's crucial to ensure sufficient contrast with text and other foreground elements. A light text color, such as white or a very pale yellow, would be necessary to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Avoid pairing it with dark text or colors of similar luminance, as this will make content difficult to read for users, especially those with visual impairments. Furthermore, be mindful of users with color blindness; relying solely on color to convey information is not advisable. Supplement the color with text labels or icons to ensure inclusivity. Large font sizes and generous spacing can also improve readability against this strong background. Interactive elements such as buttons should have clear visual cues beyond just color to indicate their state (e.g., hover, focus).
