A light brown almost caramel color is a good sign that everything is working properly. Your spark plugs in that vehicle are designed to last for around 110,000 miles and can even go higher depending on the fuel you use. You have to check the gap on the plug to determine if they should be replaced. The correct gap setting should be on a sticker under the hood or in the owners manual. As this type of plug ages it slowly wears away at the electrodes and the gap increases until it eventually will be beyond the designed heat range and then you will begin to notice performance issues like loss of power and fuel mileage. When you replace these plugs make sure to use a high grade plug with iridium tips to regain the losses. Also it is very very important to use anti-seize on the threads of the plugs before you tighten them back into the cylinder head. If you don't properly lubricate them the next time the plugs are removed it will rip the threads out of the head and is very costly to fix. I hope that I have been helpful.

The ceramic insulator should be white not brown. Did you measure the electrode gap with an inexpensive set of round spark plug gages? Denso has a new line of extra long life iridium plugs that are supposed to be good for 60,000 miles in your car. autopartswarehouse.com has them. The price may make you choke a little, @$17. and change but knowing that type of plug I'd go with it in a heartbeat.
Possibly, if you have over 50,000 miles on your car it would pay to have your fuel injection system professionally cleaned at your dealer or run a plastic can of 3M Total Fuel System Cleaner in your gas tank with no more than 14 gallons of fuel.
