i saw a quilted redwood guitar that was finished purple at some point last year - it was stunning!! I just wish i could find photo's to prove it
This is one of my early guitars that i used a nice piece of redwood on:

I really like the wood but find the colour a bit too, well a bit too orange!!
Compare that to the redwood on a huber
http://www.huber-italia.net/images/guits/redwood_lite.jpgand you have to admit Nik gets a much nicer colour from the wood.
What i wont be doing is what dean do with there redwood, i.e. cover it in a thick coat of black to hide the figure and end up with something lovingly referred to as a 'diarrhoea burst'

now if only i could fnd a nice example of a purple redwood guitar i am sure you would be convinced.
Also the redwood only cost me $25 so i am not worrying about it so much!!
