Evo VI Paint Codes

I usually only hang out in the Scale Modelling section, but maybe somebody here can help me.

I have a model of an Evo VI and I want to paint it Rhiems Blue. I've tried a couple of auto paint suppliers but none of them have a record of this colour. However they claim to be able to mix it if I have the paint code.

Anyone know the paint code for Rhiems Blue? Maybe this colour is also known by another name?

Thanks for any help.
