Question: Color issues

I have one of these and all of the reviews rave about the colors being "natural" and I have not had this experience. For Christmas my son was wearing a red shirt and it showed up magenta. Also my hair is red and I was wearing a green shirt and my hair had green tones to it as well as yellow and brown (no red). I am using all the default settings but I have played around with the others and have had no luck. I am using my basic indoor lighting I have always used with taking candid point and shoot pictures. Is there anything I can do differently?
