About International Klein Blue

International Klein Blue, represented by the hexadecimal color code #0425C6, is a deep and highly saturated shade of blue. It is named after the French artist Yves Klein, who patented the color in 1957. Klein sought to create a blue that was as pure and intense as possible, believing that it could convey a sense of the infinite and spiritual. The color is achieved by suspending ultramarine pigment in a synthetic resin, which allows the pigment to retain its brilliance and depth. International Klein Blue has been used in a variety of artistic and commercial contexts, from paintings and sculptures to fashion and graphic design. Its unique visual properties make it instantly recognizable and highly impactful.

The hex color #0425C6, also known as International Klein Blue, presents some accessibility challenges, particularly in text-based applications. Its very dark hue results in low contrast against lighter backgrounds, potentially making it difficult for users with visual impairments to read text rendered in this color. To ensure accessibility, it's crucial to use a very light color for text or other foreground elements placed against an International Klein Blue background. It is recommended that you always use a tool to verify the contrast ratio to ensure that it meets the WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is advisable. Furthermore, avoid using #0425C6 for interactive elements without proper visual indicators, as its darkness may obscure affordances, making it hard for users to identify clickable areas or actionable items. Consider adding borders or other visual cues to improve usability and ensure a more inclusive user experience.
