Hi Robbo, that looks like colourtone blue but you would need to order the stuff from USA to make sure you got the full strength stuff. I bought some cherry red and mahogany from an OZ supplier 18 months ago and it was watered down and the cherry had about as much 'Zing' as red food colouring. Ended up mixing it with fountain pen ink to get the desired colour.

DT is very unique and from personal experience I had a couple of batches of Coolangatta Gold that were different shades. First batch of Gold and Outback Sunset were translucent whilst next batch of Gold was opaque and took a lot longer and more effort to achieve the desired colour. These were all DT MkI experiences and believe MkII is now better. It appears to be more of an oily based product so mixing in other things to alter the colour is not so easy. That said, another DT colour might help and in this instance it would need to be Black Stump, just a little to make the Bondi Blue a bit darker.

Check out my EX-5 where I mixed up a brew of OS & CG and had the shock of my life when it came out bright orange as I was trying to lighten up the OS as it was a darker shade than what I had planned.

Lots of fun to be had experimenting and mixing up different colours but well worth it if straight out of the bottle is not quite what you want.
