Just be careful of whose RLM's you use.
Humbrol is pretty good.
There is a Spainish company I saw on U-tube that has water based colours you can use in your airbrush right out of the bottle and the colours are really nice.
Not to mention no smell .
There were some British companies that made really accurate colours
1) Precision or
2) Compucolour
If you would like I have a lot of it almost all various colours. With overseas shipping I paid about $3 a tin.
I would sell you some same price,and some nominal shipping price.
We had a master modeler in our club who eventually went on to found, "Accurate Models" this guy loved those paints.
Let me know
