International Klein Blue
About International Klein Blue
International Klein Blue, represented by the hex code #091DAB, is a deep blue hue conceived by the French artist Yves Klein. Klein developed this specific shade of ultramarine in collaboration with a Parisian paint supplier to perfectly capture and maintain the color's intensity. He patented the process to preserve the color's unique qualities, solidifying its place in art history. This blue is celebrated for its remarkable saturation and visual impact, which Klein saw as representing the boundless expanse of the sky and the sea. In art, International Klein Blue aims to evoke a sense of the infinite, unburdened by form or representation.
The hex color #091DAB, also known as International Klein Blue, presents some accessibility challenges, especially when it comes to text and background contrast. Its darkness necessitates careful consideration of foreground text colors. White or very light shades of yellow or green are generally recommended to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards for color contrast (minimum ratio of 4.5:1 for normal text and 3:1 for large text). When used for interactive elements like buttons or links, it's crucial to provide clear visual cues on hover or focus states, as color alone shouldn't be the sole indicator of interactivity. Consider alternative, lighter tints of blue or the use of borders and icons to enhance usability for individuals with visual impairments or color blindness. Thorough testing with accessibility tools is advisable to validate contrast ratios and ensure a positive user experience for all users.
