Im going to use black coloured natural and chemical dye. This way the colour changes will be more obvious. The controlling of the dye colour will also be another independent variable.Here's some more info on Henna and chemical dye:
Henna is a flowering plant, scientifically called Lawsonia inermis. Its uses include the dying of skin, hair, leather, fingernails, wool and a few other fabrics. The art of Henna dying has been practised since ancient times, with origins from the India and the Middle-East.
Chemical dyes are manufactured products, the ones we normally see on shelves in Coles or Woolies or used in hair saloons. When applied to fabric, these dyes undergo a chemical reaction. The fibres of the material are subjected to a change in PH level in order to help the particular colour bond to it. Acid dyes are usually used on protein fibers like wool, silk and other animal based fibers. Basic dyes are used more on cellulose fabrics like cotton and hemp, though they still work on protein fibres but are less effective.
