Giallo Fly 20-Y-191, need help with formulation

Alberto,

Thank you for your reply. I appreciate that there can be very minor variations in tone between batches even if you are using the same paint supplier and formulation. This was not my primary concern. I have seen multiple instances where a particular colour mixed to a published formula looks considerably different depending on what paint manufacturer is being used. When I say considerably I mean that if you have a good eye you do not need to have two samples side by side in order to notice. It would seem that based on your experience that is not the case here.

Regarding the use of a white basecoat this was also recommended to me by the local representative of House of Kolor (known for their hot rod paints). Apparently the modern yellows are among the worst colours for hiding/coverage due to the absence of lead in the pigments. I was told that the white will not only enhance the brightness of the colour but is also a good step to ensure that the colour looks even in all light conditions. For my own interest I am going to have one test panel painted with a black base and one with a white base so that I can see first hand the differences involved.

Kind Regards,
Paul

 

This was a yellow by PPG that was used in many standard and custom colors DMC905 Lemon Chrome Yellow. First banned in California and I assume nationwide due to its lead base.

 

Yesterday my Dino 246 GT parked beside a Dino 246 GTS.
Mine is from 71 with the old Giallo Fly 20-Y-191 and
the GTS has the new Giallo Fly 20-Y-490.
The yellow look always different depending on the light, but see the interesting picture:

Perhaps I should make that eye doctor appointment, but I didn't really notice much, if any, difference between the two when you factor in the camera angle + direction of lighting.

 

Try this one, shot from the roof within the same minute/light situation

Whew! I can cancel that urgent eye doctor appointment now! Thanks for the great shot that clearly shows the difference. Glad my 71 Euro GT is the same 20-Y-191.

 

Hi everyone,

I would like to confirm that my 1971 246GT is earlier fly yellow, 20-Y-191.

The production month/year is August 1971, the VIN is 01150

How do I describe the official color name and color code when I go to PPG store?

Thanks for your answer in advance.

Regards,
Vincent

 

yes, that`s correct....

 

Alberto, my car was painted in 1997, in Italy, and they sent me this. No clue if that makes it "correct"
