My whole family has blond, green-eyed looks, while I have dark brown/black hair and eyes with tanned, olive skin. We are Irish/German. Why would I be the dark looking one?

It is because of your genetics. Your genes either skipped a generation or both your parents were heterozygous for blond hair and green eyes, and you just happened to be the 1/16% to inherit both genetically. That is probably over simplifying it quite a bit because of how there are also epigenetics as well where multiple alleles will affect how your genes are expressed such as height. If there were only two alleles for height than all people will be either tall or short and no where inbetween. I'm not sure if barr bodies affect the eyes or hair but because you are a female and barr bodies are in all living cells, you are basically a genetic mosiac. Meaning that because you are a female (XX) one X chromosome will condense so that you do not have more X than a male (XY) and thus dosage compensation. The kicker is that it is random in each cell which X chromosome is condensed. An example would be a calico cat where they can show all different colors of fur. Again I doubt it is the Barr bodies but probably the skipping of a generation(s) or just your parents both are heterozygous.
TLDR: Nature doing what nature does best, nature. Nothing to be ashamed of because you looking something fierce.0
