International Klein Blue
About International Klein Blue
International Klein Blue, also known as IKB, is a deep blue hue first mixed by the French artist Yves Klein. Its striking vibrancy and unique matte finish quickly became emblematic of Klein's artistic vision. Chemically, it is a ultramarine pigment combined with a synthetic resin binder, which allows the color to maintain its intensity and velvety texture. IKB is often associated with concepts of infinity, spirituality, and the immaterial, reflecting Klein's interest in transcending the limitations of physical reality. It is considered a distinctive and recognizable shade of blue, widely used and referenced in art, fashion, and design.
The hex color #0315b0, also known as International Klein Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value creates poor contrast against white or light backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #0315b0 falls far short of these recommendations when paired with common background colors, failing WCAG AA standards. To enhance accessibility, consider using lighter shades of blue or pairing it with contrasting colors like yellow or white. Tools like contrast checkers can help evaluate and improve the color's accessibility for diverse users. Proper contrast ensures readability and inclusivity for individuals with low vision or color blindness.
