International Klein Blue

General Information about #0321B0 (International Klein Blue)

The hex color #0321B0, often referred to as International Klein Blue (IKB), is a deep and saturated shade of blue. It's defined by its intense and almost velvety appearance, making it visually striking. This particular shade of blue is named after the French artist Yves Klein, who patented the unique hue for his artwork. IKB is created by mixing a binding medium with a pure ultramarine pigment. Its distinctive quality lies in its ability to evoke a sense of depth and infinity. In color theory, blue is often associated with calmness, stability, and trust, but in this intense form, it can also convey creativity and innovation. The hex code #0321B0 signifies a specific combination of red, green, and blue values, with very little red and green, and a dominant presence of blue, defining its strong blue character.

The hex color #0321b0, a deep and intense blue, presents significant accessibility challenges, especially in web design. Its low luminance value means that text or interactive elements using this color as a background require extremely light foreground colors to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text to comply with WCAG guidelines. Using a color contrast checker is essential to verify compliance. Avoid pairing this color with dark shades or colors of similar luminance, as this will render content illegible for users, including those with visual impairments. When used as a text color, #0321b0 should only be used on a very light background, such as white or very pale yellow, to maintain readability. Consideration should be given to users with color vision deficiencies, who may struggle to distinguish this color from other dark shades. Proper testing and evaluation are crucial to ensure that content remains accessible to all users.
