Someone posted this list in an earlier thread:
1. Orange Crush: RAL Code: RAL 2000; PANTONE 7579 C
2. Silver Spectra: RAL Code: RAL 9007; PANTONE 422 C
3. Dr Mayhem Grey: RAL Code: RAL 7012; PANTONE 425 C
4. Black Magic / Mark III : RAL Code: RAL 9005
5. Ice Queen / Baker Express - White color: RAL Code: RAL 9010
6. Ravishing Red - Red Color RAL Code: RAL 3001; PANTONE 200 C
No idea if its accurate. I would get a tiny sample touch up bottle made to test it before going ahead and ordering a few litres of it
Note a RAL colour gives you a base solid color but if the paint is metallic that will change things a lot.
