New hair? Cut and/or color?

So I need to change my hair! I've had it like this for the past 5 years and I'm sick of it. It's long and straight and brown and boring. I want to chop it off and color it but idk if it would look good on me! Help!! I have a big forehead too so I'm thinking maybe a fringe would look good but I'm not sure if it would work with my face shape as my jaw line is more squared off. Here's some pictures I like. Should I cut it and color it lighter or darker? 
Here's a couple pictures of me:
