Material-components-android: [colors.xml] Colors are not consistently named.

[Gryzor]

Description:
When watching the Developing Themes with Style (Android Dev Summit '19), Chris Banes, and Nick Butcher mentioned more than once, that we should _name our resources consistently_; it even uses _colors_ as an example: instead of naming them primary_color, it's preferred to use a meaningful name, like: blue_500.

This is not the case with this app, oriented at showcasing "the good practices" of working with themes/styles.

Expected behavior:
Colors are consistently and correctly named.

Hey Gryzor, thanks for submitting this issue!

I'm working on updating the theme builder to be consistent with other guidance we have (https://github.com/material-components/material-components-android-examples) as well as Nick and Chris' talk at ADS.
