LOL- is no problem really - will take 10 mins to match the colour by hand - there will be no more than 3 base colours to it. Ill match it to my Pantones, buy some Humbrol tins and mix them all together to the correct shade.
if its a touch up then my trick with the hole in the paper and spray Poly/thane will fix the paint solid and youll never notice it.
There is nothing better ( as a restorer) than having mates round and playing "spot the touch up" on a PF - if they cant find it - you did a good job
