Lotus laser blue

[nicebutdim]

Hi, I am about to have my caterham 7 re-sprayed and have fallen in love with laser blue ,I am to provide my paint guy with the correct code but I gather there are two different shades B85 or B120 which changed around 2005 ? I am after the shade with more of a metallic flip to it if any one can advise on the correct shade ?
Thanks
Dan.
