cheers guys, you've been a great help
matcos, looking through your resto thread, especially the super shiny engine bay bits, that is the exact colour i want, so i will go with the 4 2 code
this is also the colour im after, as even on a dull day you can see its the lighter brighter shade, so big thanks for digging that pic out for us paul
got a mate who has started doing mobile paint repairs coming out, so we will mix up a small amount of 4 2 coded paint, and test spray some, and fingers crossed get the right outcome
altho im expecting it to come out aubergine now with how confusing this is becoming
