Many codes are moving towards the use of Green exit signage.  This is due to the fact that the internationally recognized colors are Red for Stop and Green for Go.  Alot of jurisdictions in the Houston area are moving to the requirement of green by amendment.  

The model code 2012 IBC does not specify the color.  

I hope this helps.

Here is the link to Wikipedia on exit sign. It kind of touch on the answer to your question.

I don't really know the real answer but I am wondering if the red is due to red light having the longest wavelength and can penetrate smoke better than other colors.

Does anyone know the why the required exit signage at a door, is either Red or Green in color ?  Some are GREEN and some are RED. The California Fire Code, section: 1013.6, states it shall be in " HIGH CONTRAST WITH THE BACKGROUND".  Any feedback would be greatly appreciated. Just had that question asked to me...
