But these natural colors are now being marketed as specialty fibers that, up to now, go through the textile manufacturing process without being dyed. The colors expressed within the existing gene pool of global cotto ns are limited to brown, red and green spectra; shades may be varied by blending these fibers with naturally white cottons and with other colored cottons. It is well known that the cottons designated as being naturally white are not uniform.
