Abstract: Dyes were extracted from the stems, roots and leaves of Rubia cordifolia Linn., Morinda angustifolia Roxb. and Tectona grandis Linn. f., respectively and the dyeing behaviours of the colour components on cotton were evaluated. The dyeing was carried out with and without the use of mordants and the fastness properties of the fabrics were determined. The absorbance (%) and colour strengths (K/S) of the dyes were evaluated and the colour changes were recorded in Hunter co-ordinates and converted to CIELab co-ordinates
