I'll speak up on behalf of clear ("colorless") glass.
For a number of years through the last three quarters of the 20th century, a number of the best glass houses (Steuben, Waterford and Baccarat come to mind) produced only or mostly high-quality, uncolored pieces of lead crystal. It was a conscious aesthetic and philosophical decision, derived from notions of purity based in the Modernist movement.
It was felt that forms and surfaces should serve as their own decoration, and that color should be unnecessary and it was a crutch used by poor artists to hide their weaknesses and shoddy workmanship, in the way things like moldings and wallpaper were used to cover up poor construction in houses. These notions came from architects like Mies van der Rohe and Walter Gropius. (It's been suggested that their position may have been because they were simply lousy colorists and I think in Mies' case, there's merit to that argument.)
An American architect (who lived most of his life in my hometown of Philadelphia) summed it up well when he said, "Let brick be brick. Let stone be stone. Let wood be wood." And by extension -as Stueben did after they fired Frederick Carder- glass should allowed to be simply and completely transparent.
I think there's a valid point there, and at the moment, most of my own, personal collection consists of big, solid, bold pieces executed in crystal. I'm especially fond of the massive, blown and cut pieces Orrefors made in the 70s and 80s. They're solid, sculptural, architectural.
And I find that crystal pieces do display well: they mass together, and overlap, reflecting and refracting light. I have a big bow window in my living room, looking out onto the street, and the sill is full of all sorts of pieces of crystal, jostling for space with each other.
The other nice thing about pieces in crystal is that they play well together. It makes mixing pieces from different countries and different times very easy.
I like color. I understand color, and it's place in glass (imagine how boring Murano glass would be without color!), and when I'm buying for resale, I'll always buy colored pieces before crystal. But for myself, for the moment, I like big chunky pieces of crystal.
