International Klein Blue
About International Klein Blue
International Klein Blue (IKB), with the hex code #0023B4, is a deep and intense shade of blue that was developed by the French artist Yves Klein. Klein sought to create a blue that was as pure and evocative as possible, capturing the essence of the sky and the sea. He achieved this by working with a chemist to develop a unique matte synthetic resin binder that allowed the pigment to retain its brilliance and intensity. The color was officially patented as International Klein Blue in 1957. IKB is more than just a color, it is a piece of art history. This specific hue of blue has become synonymous with Klein's artistic vision, representing the infinite and the immaterial. It has influenced various fields of art and design, remaining a prominent color to this day.
The color #0023B4, a deep and vibrant blue known as International Klein Blue, presents specific accessibility considerations for web development. When used as a background color, it's crucial to ensure sufficient contrast with foreground text and interactive elements. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA guidelines. Using a light color such as white, or a bright yellow or light green can provide sufficient contrast. Using a dark shade of gray or black as text color would make the text unreadable. Tools like contrast checkers can help verify compliance. When used for interactive elements like buttons or links, hover and focus states should be clearly distinguishable, again ensuring sufficient color contrast. Furthermore, avoid relying solely on color to convey meaning; supplement color cues with text labels or icons. Consider users with visual impairments or color blindness when choosing color combinations, opting for accessible color palettes that cater to a wider range of users. Proper implementation ensures an inclusive user experience.
