"I am also trying to collect as many different paint charts as I can find
since 30 yrs ago it was FS only and you mixed your own. So any help out
there would be appreciated."
Remember, printing ink and monitor colours and the actual paint will NOT be indentical.
There is no substitute for real paint chips. My solution, every time you open a bottle, you brush or spray (or both if you can) the paint onto a 1inch square piece of white polystyrene for the truth of what is in the bottle. Keep the chips out of sunlight too :)
