Another option to maybe not being so permanent with your funkiness, would be to actually buy some of these fake strands of hair, that can easily be inserted into your look. If you find them here on a booby pin, this would probably be the thinnest version. Some of them come a little wider on some clips. What you can easily do is section up some hair, put your bobby pin inside and then you bring it back down to hide it, and there you have a little bit of color, without the permanence. So I think that could be a nice little tip, if you're not ready to dive all the way into the hair color.
