There is a lot of different things. If its green its radiator coolant. If its orange its probably transmission fluid. Black Oil. Check all your gauges and dip sticks and see if one is low.

Gas or oil leak? Gas leak can turn the light on. Oil doesn't. Try to notice where the leak is under the car on the ground. Look under the car and see where the leak is on the frame. All this helps. Have the codes read.
I don't know what you are driving..but sometimes the leak that you see under the car starts in the front area and runs to the lowest point and drops off...try getting under the car or up on a lift..follow the tale tale signs of the water/antifreeze running olong the underneath of your car...my bet it your water pump is starting to go bad..they have a small weep hole at the bottom of its shaft..if the seal/bearing is wearing water will start to leak and run along the underside of the motor..good luck..
SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.
CHECK UNDER VECHICLE IF TRANSMISSION FLUID UNDER TRANSMISSION MORE LIKELY PAN GASKET LEAKING FLUID.IF FLUID HAS NOT BEEN CHANGED THE PAN GASKET GET HARD LEAKS FLUID.THATS IF YOU HAVE SLOW LEAK.IF YOU LOSING LOTS OF TRANSMISSION FLUID ITS .LEAKING AT TORQUE CONVERTER SHAFT SEAL.LEAKING AT COOLER LINES.CHECK COOLER LINES FROM RADIATOR TO UNDER CAR WHERE COOLER LINES GOES TO TRANSMISSION. AND CHECK LEAKS AT FRONT DRIVE SHAFT AXLES SEALS
OIL LEAKS UNDER CAR COULD BE COMING FROM LEAKING OIL FILTER OR OIL PAN GASKET.CHECK FOR OIL LEAKS AROUND REAR MAIN OIL SEAL AND FRONT TIMING COVER CRANKSHAFT SEAL LEAKING OR LIP SEAL AT THE LOWER TIMING COVER TO OIL PAN.
SMELL GAS YOU NEED CHECK ALL FUEL LINES UNDER THE HOOD IN THE ENGINE COMPARTMENT.IF GAS IS STRONG UNDER HOOD YOU DONT SEE LEAKING FUEL LINES.YOUR FUEL RAIL FUEL INJECTORS LEAKING OR FUEL PRESSURE REGULATOR O - RING OR DIAPHRAM LEAKING GAS.IF FIND NO LEAKS UNDER THE HOOD CHECK FUEL LINES UNDER CAR FROM ENGINE TO FUEL TANK FOR LEAKS.IF ALL IS GOOD YOUR EVAPORATIVE CANISTER SOAKED WITH GAS OR YOUR EMISSION EVAPORATIVE SYSTEM NOT WORKING. DEALERSHIP HAS TO CHECK AND FIX.
