"Guide to Finger-Print Identification" by Henry Faulds (1905) mentions colored sweat. Page 65 states:
"There is, however, a curious affection called Chromidrosis, in which the sweat is coloured. A blackish ooze takes place in some hysterial cases. More striking is the class of cases in which the colouring matter is derived, like the bright colours in the plumage of parrots, from copper, and in some cases, from iron. Workers in copper have been found subject to it. The sweat is generally of a bluish colour in those cases. Red sweat has been observed in lock-jaw. A kind of saffron colour I have found to be not very uncommon in some classes of malarious cases...."
My question: has anyone in law enforcement seen red, blue, yellow or black sweat when fingerprinting suspects or victims in the recent past?
