Hi Diggy Dude,
I ordered a custom Dingotone in rosewood once. I just contacted adam to get the ball rolling. I expect you could also contact the new fella Ben as an alternative.

It did take a while though as Dingobass had to test the colour etc to make sure it was all good. I was not disappointed either.

A quicker option I suppose would be to order a colourless kit and use some of your own dyes with it.
