Here is another reference, Iso Grifo colors https://mycarquest.com/2011/05/iso-color-samples.html Note, the sequence of the Iso colors is different from the Goose roll in that the metallics are separated from the solids, but in both cases add up to (5) red shades 
So if you want to go a really orange Rosso Dino (Ferrari name for probably what here is Rosso Aurora), or even the metallic, and still call it a factory RED, now is your chance Lee
Iso Color Samples
by Mike –
Iso offered 24 exterior color choices, maybe more, there are 24 on this sample kit but there could have been others. This is a large selection for a small company and different than the Henry Ford philosophy of “any color you want as long as it is black”.
These pictures show an original Iso color sample kit. I am sure that some, or all, of these same colors were offered by other Italian car manufactures in the 1960s.
Below is the back of the color samples where the color names and codes are printed.
Here are the 24 colors.
