What color should I dye my hair?

I have pale skin, freckles across the bridge of my nose, blue/green/grey eyes and pinkish lips. I have a mostly irish complexion. My natural hair color underneath is a medium brown with streaks of golden blonde on most of the top. I really want to try something new but am too afraid to wing it/ don't want it to look bad. It can't be anything too unnatural like blue or green but red, brown or blonde would be in bounds. Thanks so much for the help!
