Parameterized blueprint or selector combinator for train station color

[burninghey]

While setting up my train network, I love how trains change color depending on target station.

Now, with parameterized blueprints, I thought that's an easy way to change station color. No, color is not in there.

Reading the item type, selecting a color and sending this to the station would be another way. No, not possible either.

This leads to 1 blueprint for every single type of cargo, which is exactly what parameterized blueprints aim to change.

I discovered that if the parameterised station name matches an existing station then it will use that colour. So I made a reference area with just stations to set all the colours and then have parameterised blueprints that include the station and whatever else I want.
