About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0324c5, is a deep and vivid shade of blue renowned for its intensity and unique matte finish. Named after the French artist Yves Klein, who famously registered the color, it embodies a sense of ultramodern artistic expression. This distinctive hue is created through a specific formulation of ultramarine pigment, lending it its unparalleled depth and saturation. Klein believed that this particular shade of blue could convey the purest expression of color, free from representational meaning. It's often associated with concepts like transcendence, spirituality, and the infinite. Its historical and artistic significance makes it a sought-after color in design and creative fields.

The hex color #0324c5, also known as International Klein Blue, presents significant accessibility challenges. Its very low luminance value means that text rendered in this color requires a very light foreground color to meet WCAG standards for contrast ratio. 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. This intense blue is best used sparingly, for example, as a highlight color or in large graphical elements, to avoid making content inaccessible. When using this color, thorough testing with accessibility tools is crucial to verify compliance with accessibility guidelines and provide an inclusive user experience. Consider using a color contrast analyzer to determine appropriate foreground colors and adjust the design accordingly.
