headlights one is normal the other headlight a different color

Did you recently change that bulb? If not, it may be getting ready to blow. If so, you may have put in a different kind of bulb.

Bulb mismatch is probably the reason. And here is a suggestion. When replacing headlight bulbs DO NOT opt for the much higher price bult which will light up the road like a football stadium. Unless, of course, you live in a rural area where slamming into a cow on a unlit road is a possibility. The brighter bulbs do not last as long at the standard brightness bulb. And if you take the time to read the back of the blister pact it will show the life expentancy of the various bulbs.
