International Klein Blue
About International Klein Blue
International Klein Blue (IKB), represented by the hexadecimal color code #031CB0, is a deep blue hue renowned for its intensity and unique visual impact. This ultramarine pigment was developed by the artist Yves Klein in collaboration with a Parisian paint dealer, Édouard Adam, and the chemical formula for the color is protected by the INPI (French National Institute of Industrial Property). Klein sought to create a blue that captured the essence of the sky and the sea, evoking feelings of limitlessness and spiritual depth. Its striking saturation and matte finish distinguish it from other blues, making it a sought-after color in art, design, and fashion. The color has been trademarked, so it has a strong significance with the artist Yves Klein.
The hex color #031CB0, a deep shade of blue, presents accessibility challenges, especially concerning color contrast. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. If using this blue for interactive elements like buttons or links, ensure that the hover, focus, and active states also provide adequate contrast. Text size and font-weight choices also affect readability. Therefore, careful consideration should be given to pairings of this color with other elements. Consider providing alternative color themes to allow users to customize their viewing experience, which is a best practice for inclusive design.
