Beauty, as Pete has said, is in the eye of the beholder & both are of interest.
For me personally the beauty of well turned wood is in the main the wood it is turned from & the form of the piece. Whilst I have no objection to some decorating & colouring on pieces they no longer hold an appeal as woodturning to me when, because of the decorating, they could be mistaken for pottery, plastic or another medium.
That`s certainly not to say such pieces are not of a good quality or indeed worthy pieces, they are, it`s just not what I personally want from woodturning.
Cheers.
