Vinegar is produced from alcohol using a vinegar culture. The color of the vinegar is based on what was used to make the vinegar and thus results in different flavors. For instance, beer tastes different from red wine which is again different from white wine. Which vinegar you use should be based on why you are using it and the quality factors, such as what it was made in, how long it aged, etc. More concern should be applied to these things than what color it is. White things aren't always bad or a result of bleaching.

Balsamic vinegar is made from grape pressings which have not been made into wine. It is aged in barrels similar to wine. It is generally very deep burgundy and slightly sweet and syrupy, depending how long it has been aged. Other vinegars such as white wine or rice wine vinegar are made from wine in a controlled process. The sugar in the mixture becomes alcohol and the alcohol becomes acetic acid in order to produce vinegar.
