[feature-request] themes or colour settings

[TheRojam]

it would great to have themes.
Even the standard theme is great, but i would like some different colours at some points.
e.g. the rotating circle is purple. i would more like with green or blue.

The angular material has 4 themes, a look at the examples page, at the top you can change the themes.

We could have these same 4 in-app theme options.

More likely I would switch to something different than Angular themes to match the application design more likely with mobile. I checked thru the code and it seems it's all covered up with css, so if no one will go with it before me, will do it ;)
