We use color to distinguish observables.

Here a [twitter poll](https://twitter.com/Michael_Hladky/status/1070326940480012288)

The outcome of the poll, as well as further offline discussions, ended up in using color for observables. A good example is combination, or flattening operators. 
Here one color per observable would be very intuitive.
