Just to make it clear for all you Copic users out there - below is a link to our website where we've got a PDF document I've written with Copic comparison colours for all the Promarkers I use. I know I've put a list at the beginning of each video - but the colours I refer to when I'm colouring are all Promarker colours. I thought if you have this it's much easier to look up the Promarker I'm using and find the corresponding Copic colour.
Sorry it's probably a bit waffly but hopefully it's makes enough sense!
