Orange flames ???

My furnace is a Carrier Model 58pap070-hc about 12 yrs old. Works fine, good heat, no funny noises or smells. When changing the filter I noticed the flames on the burners where orange instead of the usual blue. When only pilot is lit, it burns a steady blue. Note on furnace shows thermocoupler was replaced about 5yrs ago. What is causing the orange flames and how can I fix this??? Thanks.

First would be check the gas psi or W/C. Then check and see if burners venturi are clean and check the air inlets and adjust them. Also when the burners are on tap the side of them with a screw driver some . See if that might clear them up.
