I wouldn't say I prefer colourless, but I have a lot of it. At a certain point when I started to collect German glass, I moved towards Peill & Putzler and Nachtmann, and most of their truly striking pieces are colourless. However I do prefer pieces that are well textured. The sort of simple clear pieces that became the norm for cheap flower vases from the 80's onwards don't really work for me.
I think I was sold when I saw one of these big bold Strombergshyttan Viking ship pieces up close. These big bold chunky crystal pieces really blow me away.
Displaying them can be somewhat of a problem so I can't really add much to that question, because they don't look so well against my white glass curtains, but that doesn't diminish the beauty. I can't resist showing a few pieces that I love, even if they don't photograph well (well at least, I can't seem to find a good way...)
