Basic Green 4, famously known as Malachite Green, is a powerful triarylmethane dye that produces an intense, bluish-green colour. It is a workhorse colorant used across a wide range of industrial applications due to its exceptional tinctorial strength, making it a very economical choice for achieving deep, brilliant green shades. It is used extensively for dyeing paper, leather, and acrylic textiles where a vibrant, impactful green is required.
