What color tube is drawn for glucose?

It could be either red top (to clot it) or Grey top (sodium fluoride or potassium oxalate added) which prevents RBC's from metabolising the glucose in the blood. There is also another one to separate the serum but I forgot the color. It might be "tiger top" or speckled.
