Abstract	Silk is one of the most beautiful and luxurious textiles in the fashion industry. The conventional process of obtaining silk involves killing the silkworm before it gets ready to emerge from the cocoon. But the cocoon formed is naturally white in color, and its wide requirement is in various colors, so in order to obtain silk in various colors, artificial dyes are used on silk, which contain high concentration of toxins, thus resulting in water pollution. There is a high demand for a sustainable and environment friendly option to reduce this damage. Thus, Bombyx mori silkworm larvae are fed with a modified feed of mulberry leaves sprayed with synthetic dye solutions. While some dyes did produce an intrinsically colored silk cocoons and some did not, this process if implied will significantly reduce the need and effects of dyeing which are generally observed in the traditional methods. After carefully evaluating the physical properties of the synthetic dyes used, we have noticed that the balance of hydrophobic and hydrophilic character is extremely necessary for the diffusion of the dye from the alimentary canal of the silkworm larva into the hemolymph and later into the silk glands. These insights are extremely important to be considered in development of novel dye molecules that can be successfully fed to Bombyx mori silkworm larvae for producing colored silk of various colors and shades. Silkworm larvae in their fifth instar are fed with modified diet prepared by dipping mulberry leaves in synthetic dyes. Colomill red, colocid blue, colocid violet, colomill maroon, colocid green, colomill yellow are the synthetic dyes used. Besides these kesar yellow and lemon yellow are the two food colors used in this experiment. Colored cocoons are produced by three experimental groups which are feed with modified diet prepared using colomill red, colomill maroon and colomill yellow.
