International Klein Blue
General Information about #031EB0
The color #031EB0, also known as International Klein Blue (IKB), is a deep, vivid shade of blue known for its intensity. It was created by the French artist Yves Klein, who sought to capture the purest expression of blue. Klein patented IKB to preserve its unique qualities. This color is notable for its high saturation and slightly violet undertone. In the RGB color model, #031EB0 is composed of 1.2% red, 11.8% green, and 69% blue. In the CMYK color model, it comprises 99% cyan, 83% magenta, 0% yellow, and 31% black. Its hex code #031EB0 makes it easily identifiable and usable in digital design and other applications.
The hex color #031eb0, a deep shade of blue, presents significant accessibility challenges, particularly in web design. Its low luminance contrast with white text necessitates careful consideration of color pairings. According to WCAG guidelines, 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. Given its darkness, #031eb0 is best paired with very light colors like white (#ffffff) or very light yellows (#ffffe0) to meet these requirements. Using it for text on a dark background or with colors of similar luminance would make the content difficult or impossible to read for many users. For elements like buttons or links, providing clear visual cues beyond color, such as underlines or borders, can further enhance accessibility.

When used in makeup, it pairs well with neutral or metallic tones to balance the boldness and prevent overwhelming the overall look.
