Which of the following dyes are used for dyeing without a mordant?

Colouring materials have been used for many thousands of years by man. The two old ways were to cover with a pigment (painting), or to colour the whole mass (dyeing). Pigments for painting were usually made from ground up coloured rocks and minerals, and the dyes were obtained from animals and plants. However, some of our most common dyes are still derived from natural sources. These are termed natural dyes.
