General Information about International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0839AC, is a deep and striking shade of blue. It is named after the French artist Yves Klein, who registered the color in 1957. Klein sought to create a blue that captured the essence of the sky and sea, believing it represented boundlessness and spirituality. This specific shade is achieved by suspending ultramarine pigment in a synthetic resin, which preserves the color's intensity and vibrancy. Due to its distinctive hue, International Klein Blue has become a symbol of artistic expression and innovation and is regarded as a color that evokes creativity, tranquility, and depth, and it has found applications across various fields.

The color #0839AC, also known as International Klein Blue, presents some accessibility challenges. With its dark hue, it is crucial to ensure sufficient contrast against background colors, especially for text. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. When using #0839AC as a background, light colors like white or light yellow would be suitable text colors to achieve sufficient contrast. Conversely, using #0839AC as text requires a very light background. It is essential to test color combinations with accessibility tools to confirm compliance and ensure readability for users with visual impairments. Furthermore, avoid relying solely on color to convey important information; use alternative cues like text labels or icons.
