Thanks for commenting Derek, do you mean the actual colour, or the way the colour has taken?
I was aiming for something similar to the colour of the little Oak pot (below) Obviously the wood being different, a different effect is achieved. The range of darks and lights on the bowl are from the feathering in the grain and that flashes from dark to very light as the bowl is turned in the hand, it looks pretty effective then.
The deep varicoloured items I had done previously work well with a fine grain like Sycamore, but Ash is tricky to colour as the end grain takes so much more pigment as this makes it really stand out, as such I find it gets far too busy with a lot of colours and I prefer a single or two colour scheme where the enhancement of the grain can be better appreciated, it sort of a halfway house between colouring and leaving it natural.
