Rowe suggested mechanisms by which the stain forms colours..

According to Rowe, the staining of fibers by iodine stains is a colloidal phenomenon, involving the uniform adsorption of small particles of iodine on unhydrated lignin to give a yellow colour. Complexes around cellulose hydroxyl groups form colours that change with the size of the complex and the colours vary from orange, to red, to violet, to blue.
