Implement a color theme

[wrigh393]

We are currently looking into creating an appropriate color theme for the project. We will be using Purdue color guidelines as well as the Material Design color system to create this theme.

In development so far, we've been using the default theme provided by the Material UI framework. This theme provides a great deal of plumbing for us to make easy, programatic color usage, however, the default colors are iffy.

We're now looking for input and idea about a primary and secondary color to implement according to the Material Design color system.

After a conversation with Justin, Sundeep, Seth, and Allie we settled on this as our theme. We also discussed that moving forward we need to be conscious about the colors that we will use to differentiate between the different queues.

These colors will need to be revisited to work with #19
