I have written about Shiva lingam changing Colors in many temples,some changing every Muhurtha,in Tamil Nadu.
There are two temples where Shiva linga changes colour,in Karnataka.
One is near Bangalore,The Virupaksha temple,which also Cures Autism.
Another one is near Mangalore.
There is Kalyanasundareswarar temple at Nallur,Tamil Nadu.
There is another Shiva temple near Chennai.
The Shiva lingam has ,as His Accoutrement,a Stem,which resembles the Stem of Lotus.
The dilapidated temple has recently been renovated and poojas are done twice a day.
