How to create a vintage amber stain ?

[donnyb]

Hi ,
I like restoring 70's Yamaha guitars, but have not found a very close vintage amber stain to add to the acrylic lacquer spraygun finish.

I use Dulux Prooftint stains, of which I have a lot of different colours. For amber, I mix yellow, (golden teak), red (maple) and a bit of brown, but usually end up with a colour that's either too yellow or orange. I guess I have just not got the right ratios or am missing a colour in the mix, but man, I have tried a lot.
The USA has vintage and medium amber solvent based stains, but wont ship to Australia due to flammability.

In the photo herewith of a FG151B 1979, the colour I'm after is the darker amber areas on the soundboard.

Hoping someone has mastered it, or can point me to a premixed amber stain that's available in Australia and most importantly, compatible with spraygun application acrylic lacquer.

Cheers and thanks for reading.
