The document said AR101 is also bianco spino?
Does any one have a paint code sticker on a 1966 to 1967 GT Veloce or 4 door that says AR101?
Bianco spino is white hawthorn, the flower would be the obvious white.
Notice that the dark brown parts of the flower contrast well with the white petals, which would explain why the dark brown leather interior looks great on a bianco spino painted car.
I was in the Adelaide hills on Sunday for a drive and noticed there are wild Spino plants (Hawthorn bush) which just so happen to be in blossom, and yes the flowers were white (bianco) as per the photo.

Here is another document (from manufacturer of paint), listing AR101 and AR013 on the same row, meaning? they are the same? I guess.

Thanks Ruedi,

My painter made up a test panel using his computer to source the formula for AR013. The panel was very intense white when I put it in direct sunlight. Since we are using modern paints, he showed me the modern components for the mix for AR013. Black was there as well as the white and the third was an ocha/yellow (not medium blue). I will check which ones exactly and the amounts as per his paint system.
Since the interior will be red and on his recommendation I opted to stay with the computer formula as the ocha/yellow (590 to 610nm) was closer to red (610 to 750 nm) in the spectrum than the medium blue (435 to 480nm) to avoid a large separation withe red lather interior see photo or say a clash, probably subjective.(not the easiest to photograph)

Regards Steve

Hi Reudi,
I have given some thought to your research and have come up with some possibilities
The factory was making the GT Sprint 1963 to 65 in seven exterior colours (21,850 cars) and the GT Veloce (12,499 cars) had 13 exterior colours. So the proportion (a guess) of white cars may have been higher for GT Sprints, which may have highlighted some issues the white painted cars had. It could be they just did not look quite right (clashed with their interior colours). When it came to the special Bertone DeLuxe optioned cars with leather interior the GT Sprint 1963 to 65 had about 5 leather colours. While the GT Veloce had 2 colours red and dark brown.
Even though 1 drop of medium blue #1070 is not much in AR013, it may still be enough to make the red and or the dark brown interiors of the GT Sprint not look quite right. So what to do? just remove the 1 drop of medium blue #1070, thus reducing the clash with the red interior, and it probably made no difference to the dark brown interior. This could only be done when a new model was introduced, other wise a nightmare in warranty claims if colour was changed mid stream of production of GT Sprints, repairers would be going crazy trying to work out what the original white colour was so as to match the panels, remember we are taking before colour meters and only the best skilled painters had the luxury (at a cost) to experiment on test panels until they matched the repaired panel with the rest of the car.
So when the 1966 GT Veloce was painted it may have been painted only white AR101 #1051 (100.0 %), looked better
and went well with the leather optioned seats of red or dark brown.(possibly removing the other three leather colour options because they were more likely to clash with the increased number of exterior paints)
Or it could have been just cost cutting and efficiency gains, consumer demand (no black GT Veloces produced).
Reduce the number of leather interior options, increase the paint options from 7 for the GT Sprint 1963 to 65 to 13 for the GT Veloce 1966 to 68. Thus remove one step of paint mixing at the factory to make up AR013, and use AR101 instead. So I'm thinking GT Veloce cars 1966 to 68 could have all been painted AR101 #1051 (100.0 %) not AR013!

Thinking that AR-101 was 100.0% #1051 may be jumping to conclusions

Sure AR-101 may not be 100.0% #1051. I will see if my painter would make up a test panel of 100.0% #1051 (say the modern equivalent) and see what the difference is.

I've seen some of the test panels of the 8C 2900B that won Pebble Beach this year. Three panels came from the same gallon of paint (and same paint preparation and solvent ratios, etc), and each one of them looked different from the others (one neutral blue, one reddish, one purple -- again, from the same gallon of paint). It drove Ian, who painted the car, nuts. He ended up believing that the difference may have come from differences in drying time (but he thought temperature, humidity, and lighting were reasonably controlled in the paint booth) or waiting time between coats, which may have affected how pigments settle in each coat of paint.

The reason why the car seemed bluer is that fluorescent lights enhances cool colours such as blue.

He ended up believing that the difference may have come from differences in drying time (but he thought temperature, humidity, and lighting were reasonably controlled in the paint booth) or waiting time between coats, which may have affected how pigments settle in each coat of paint.One funny thing with this car was that it appeared to become bluer the longer you looked at it. First, it seemed almost black, but when being in the sun for 45 minutes, and pushed back into the shop, it looked bluer than before. I wondered whether to trust my eyes and my memory (my brain may have adjusted to the light), or if the sun (and UV) exposure created some fluorescent effect in the paint. I'll never know. The same thing may happen with shades of white.

One of my painters who is in his 70's had specialised in colour matching in his 20's and I think he said he 'prior to colour meters' would use his eyes and test match a sample panels with the rest of the car outside the shop in sunlight, prior to painting the actual repaired panel (to get away from this blueing effect under fluorescent lights)
My suggestion in painting a whole car may need a different strategy so that all the panels match 'in sunlight' where and when the judging is done.
If say your car is being judged at Pebble Beach on 19th August 2019 then I think you have to first guess what the weather (amount of sunlight) will be like on 19th August 2019 and paint your car under controlled conditions (say on a day that has the same amount of sunlight as there will be on 19th August 2019, say around August 2018). Don't forget to take into account the surrounding effects of the water and the landscape of Pebble Beach, including the lawn, grass it sits on while being judged!
I thought as soon as you introduce variability in some processes, you may get variability of outcomes. May be the number of coats and drying times between coats needs to be kept the same as you have found out.
So are the judges at Pebble Beach, the painters of cars and owners of cars in their 20's? I don't know, like you implied younger eyes are probably better at judging colour differences.

Just happen to get from Notch (Aka Paul) who was kind enough to supply a photo of his newly acquired one owner 1967 GTV paint code (car's colour is white) do these link in with your database? The S12535 is the primary colour the car was painted, while S13444 is the touch up paint in enamel.

 

[Steve105]

Hi Notch,
I suspected the car was ordered, and not on the show room floor.
The build certificate, will list exterior colour and city it was imported to.
The white GTVeloces were painted I think AR101 not AR013. It could be they stopped using AR101 as a code and used it's paint suppliers code S12535 (but it was still AR101)
If your build sheet says paint Biancospino then S12535 may be AR101, or a special paint order like you said. I will talk to my painter next week to see if the code makes any sense.

Cheer Steve

 

[Steve105]

I think now that the AR101 name was changed to AR013 and applied to GT Veloces 1600, which has confused it with prior AR013,of course different suppliers have their version as well.
Regards Steve

The listing is showing paint code from 1965 for AR013. This assumes the paint code for 1965, 1966 and 1967 are all the same. Since they did make GT Veloce 1600 in 1965 it's possible.

The paint sample card does show a blueish tinge to it, something that that has not been seen in other sample paint chip cards. I suspect the sample paint chip card has not been stored well and has deteriorated.
