What color wires go with each screw on my thermostat?
Question:I am new to my house yesterday, which did not have a thermostat. Out of the wall, I have a red, white, green, and blue wire. I want to install a 7 day programmable thermostat that has hookups at W, RH, RC< G, Y/Y1, O/B. I have a natural gas furnace and an air conditioner to hook up to it. I appreciate your help in advance.

Start here: http://www.toad.net/~jsmeenen/wiring.htm... and just follow the red lettering to the specific page that applies to your system.
If you read the whole thing you will know as much about the wiring as a heating and air conditioning expert.
Good luck. It really is a piece of cake...
Typically it is Red to R White to W Don't remove the jumper between RH and RC Green to G which should be the fan of the furnace and the Blue Should be B
try mixing them and see what happens
