hi tom,
the colour code number for red/black 124 abarth's is 152. between 1972 and 1974 were 3 different red's used, all by the same colour code number. it' a lighter red, a darker red and another one.
my car was painted in 1986 with a lighter red. in the sun it looks more or less like orange and in the shadow more like a blood red.
why ask you especially for the colour code for a 124 abarth. do you have an original one or are you making a replica? i just ask because i am running the international fiat abarth 124 rally register.
