Some are red, some are green. In any case, they are always brightly lit and very easy to see due to the requirement of "high contrast".
UL 924, the standard that includes "illuminated exit signs" allows them to be either red or green, leaving it to various state codes to select one, if there is a preference. NFPA 101 (Life Safety Code) does not specify any requirement for color of EXIT signs -- only that they have high contrast of the letters and background. Exit signs may usually be illuminated internally or externally.

Yes! If there is a fire everyone will need to know where to go to get out. Some national building, fire and life safety codes only require a fire exit sign if the shop is large enough to require more than one exit. A main entrance that is obviously and clearly identifiable (under all conditions) as an exit may also be locally exempt from additional exit signage. IBC 1003.2.10 (2000).

One purchase fire exit signs locally from safety supply stores and some sign stores. There are also many online sites one can purchase a fire safety sign from. Most of the online sites also seem to be safety supply and sign companies.
It is required by law to have exits properly illuminated. To ensure that each of your employees will be able to see the exit, in the case of a fire, be sure that you purchase a lighted exit sign at each exit.
An exit sign with no arrows is immediately next to or above the actual exit or exit door. An exit sign with an arrow can be away from the exit and points in the direction of the exit.
An exit sign is a device in a public facility (such as a building, aircraft or boat) denoting the location of the closest emergency exit in case of fire or other emergency. Most relevant codes (fire, building, health or safety) require exit signs to be permanently lit.
