TL;DR
Some ghost and real entities are very hard to distinguish by colour, making manually building a blueprint difficult. I think the graphics need to be tweaked to make this clearer.What ?
Can you tell these assemblers apart by colour? They are:I suggest the graphics need to be tweaked to make these easier to distinguish. The blue hint added for ghosts hides the entities colour. Reducing the saturation of this blue might help. Maybe half way between what we have now, and the grey ghosts of 1.1?
Specifically, I find it hard to tell assemblers, inserters and logistics chests apart. Here are some images comparing 2.0 and 1.1. In 1.1 the difference is obvious, in 2.0 not so much. The assemler 1 and 2 look identical, and the assembler 3 is only slightly yellower. I find telling long handed and fast inserters apart quite difficult. Regular inserters and bulk inserters both look yellow. For logistic chests: the blue hint makes the active provider blue, and the passive provider purple!
