To enable rudimentary theming, collect all colors in a new theme class. The class has to be passed down to the various items. In general the items save a reference to the them in the constructor. Alternatively, they might also just query the StatsView everytime they need to access a color. For now, it's hard the say what is preferred: a reference per item or a function call per invokation?
