is it worth the hassle?

Ballasts or ignitors are not going to change the color of the bulb. It will either be on or off if one of those is faulty. New or used. The bulb color will change over time. Normally not to noticeable as both bulbs are used together so they basically wear out together. But if you get a used set of lights or just replace one bulb then they may not be a matched set(different hours on them) and you will notice a different color from on to another. "Normally" the bulb will turn more of a yellow color when it is on the down hill. There is some factors that will add to the deterioration of a bulb such as moisture in the light, or touching the glass upon installation. Then the other reason for different colored bulbs would be different color temperatures. 3000K, 4300K, 6000K, etc. etc.

Nice to hear this. Cause I hate how my car looks with the passenger side with bueish/purple light and the driver side very bright white light. I must admit that when I bought the car (with bad ballast) I took it to a shop and they troubleshooted the headlight. They could have replaced my bulb in the proces and left installed on that was not originally mine.
