I agree, Pankaj... Another case in point is colors of Mushrooms... colors are only a guide but they can achieve very many different hues ... So are the water lilies that we find around here... hues ad infinatum... Hydrangea flowers change colors on pH or aluminum/mag addition to soil
BUT IN MEDICINE.. Addisons disease is darkening of the skin to black, Acanthosis nigricans is Black... etc etc etc very specific colors... So take home message... no hard and fast rules... at least about colors... thanks usha di On Wed, Oct 31, 2012 at 5:28 PM, Pankaj Kumar <[email protected]>wrote: > Some of very basic examples are Catharanthus roseus, what ever colour may > be all are same species. > Eulophia spectabilis: yellow, white, red, magenta: all are same species. > Colour can be taken into account if it is found in distinct zones.
