If you search this forum, you will find it has been often discussed as has the Chestnut Grey Green.
Doug Ingraham is credited for the following recipe that is supposed to be the correct red:
Using CIL base 337260 3.41can
BLK 0p8
LFY 2p0
FFR 9p0
WHT 0p20
I was not able to duplicate the green using the similar green formula but to a paint shop, these might make sense.
