Make the train station color button an actual eye-dropper tool

[esdanol]

This would just be a nice QOL improvement so we don't need to sit there fiddling with the sliders. The button could be an actual eye-dropper and set the color based on the pixel selected. Another useful approach could be applying an item to the color parameter where resulting train stop or locomotive color would be set by the item's tint.

train stop or locomotive color would be set by the item's tint.

There was definitely a mod for this in the past; IMO, it should just be a standard option. Whatever signal you pass in, the average color of that icon is used. (I have no clue what method the mod used to pick the color, from items in the chests connected by circuit. But average of non-invisible pixels is probably good enough, since most things you're transporting in bulk are mostly a single color, with shiny spots or shadows. )
