I need help with hair extension color?

So I'm going to the mall and i'm just planning on buying a cheap hair extension from hot topic or claire's or whatever, just for fun. my hair is dirty blonde, and i really don't know what color would look good on me. any suggestions?



I know this picture isn't me, and I'm not trying to steal it or anything, but this is like the color of my hair.

purple or blue would look good.
