Primary Target Audience

I am debating a couple of colors for my e portfolio, in the adobe site in class I saved a temple of them that I liked but I can't really decide. The template that I used are Easter kind of colors, pink, yellow, purple ... But I'm not sure which one to pick. I like the pink and purple better, but I'm not sure what color don't to contrast with. I think that white won't work, and will be hard to see, but I don't know how black will work either. 

As for target audience I want to try and target non profit, and show off my econ and market skills. I want to be able to show that I am mathematically inclined with the research I have done with teachers, and with the classes and papers I have wrote, but also show my marketing background as well. I want to show my work for make -a- wish. I want to make sure that I show I am diverse, and also show that I am getting my social media certificate.
