Hahahah no problem. I would use davinici rather than gopro studio if you're serious about color correction.
You could* always get a software online, but I'm not going to promote illegal downloading because downloading the legit thing is always best.
You dont need any special software, as long as you're able to create a timeline of your video you're good (like have everything laid out and final) and once you finish that you color correct it. Because lighting and colors always change in the video its best to be as specific to each individual shot as possible.
If you want something better try the GoPro studio software, they've updated it and it's sort of like iMovie but I would say better (and free). But I would just look around for cheap softwares if you want to buy yours.
Do you have mac or pc? I'll look around and see what I can find
