Definition:
SRM stands for Standard Research (or Reference) Method is the standard measure for degrees of color as related to beer and the grains used to brew it used by American brewers. It runs from 1 to around 600 with darker colors associated with higher numbers. For instance pilsner malt measures 1 while black patent malt, a grain commonly used in stout, rates around 550.
SRM is roughly the equivalent of Lovibond, the British measurement of color, and about half of EBC - the European Brewing Congress color measurement.

Examples: I was surprised to learn that Pale Ales could be as dark as 14 SRM.
