About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0f1dbb, is a deep and highly saturated shade of blue. It's renowned for its unique intensity and was specifically developed by the French artist Yves Klein. Klein sought to capture the purest expression of blue, believing it represented the immaterial and the infinite. The color is achieved through a specific mixture of ultramarine pigment and a synthetic resin binder, which preserves the pigment's vibrancy. It is seen as representative for creativity and can also be found in some flags. International Klein Blue stands as an artistic statement, an exploration of color's emotional and spiritual impact.

The hex color #0f1dbb, also known as International Klein Blue, presents certain accessibility challenges. Its high saturation and deep hue can cause difficulties for individuals with visual impairments, especially when used as a primary text color or background. The contrast ratio against white is relatively low, making text harder to read for those with low vision. To enhance accessibility, consider pairing it with lighter hues to achieve sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using tools like contrast checkers can help ensure compliance with WCAG guidelines. For crucial information, avoid relying solely on this color to convey meaning; supplement with text labels or other visual cues. Also, consider users with color blindness by ensuring important elements remain distinguishable even when color is not perceived.
