Hand vases come in a variety of colours. There's no better proof of that than this collection of vases made in the 1960's and 70's (probably of Asian origin).
This blue cased-glass vase was the very first hand vase I bought almost 18 years ago.
Note that this brown/amber vase is not cased-glass. It is transparent.
I have also seen (but not purchased YET) these vases in matte blue and green finishes. As hand vases go, these are the most common and reasonably priced.
