For this project, we had to come up with a functional application related our lives. As a result, I designed an app called Party Food, which was inspired by my friend who always likes to throw parties. Whenever she throws a party, she needs to shop for food and drink, which makes her tired all the time. The goal of my app is to solve this problem. Party Food can order a bunch of food or drinks at one time and also offer delivery service. It collaborates with restaurants so users can order food from the restaurants they love. I used orange-yellow as my primary color because I felt it could increase people’s appetites. I also used dark grey to differentiate other information from the primary information.
