Malachite Green shades

[Declasm]

I'm going to spend some time stripping, prepping and repainting my rear arches as there's quite a bit of rust bubbling up and I don't want it to get expensive. I've got a question about colour codes - I checked the colour code on my car - looking under the bonnet and found that it was 205/6 malachite green metallic. I went in to Halfords to see if they could mix me up some and their system showed either 205 or 205/D (D for dark apparently) can anyone tell me which of these shades is the same as 205/6??

DO NOT GET YOUR PAINT FROM HALFORDS

they are shit quality, and will probably mix it up wrongly.

take off your petrol cap, go to a reputable bodyshop paint susplier and match it
