Well after a few weeks of trials and disasters i have finally ended up with a perfect match.
Firstly tried Wottos bunnings colours but was a little to purple,then tried what i thought was a match in spray enamel but the colour on the tin was way different to the colour when painted,then finally found a auto paints supplier that matched the colour identically( i took him a small piece of the new decals that i will install ) and he matched it perfectly.
Had to undercoat in white firstly,then it took 3 cans to come up with the result i wanted.Bit expensive at $25 a can but well worth it in the end.

So if any ones after the colour ,the guy who mixed it,now has it on his computer base to mix the same every time. The business is at Tuggerah on the NSW Central Coast so if you needed some you would have to get it shipped from there,

Might help some of you guys out if you ever needed the exact colour,

Cheers
