Mazda Cosmo Paint Colors

There were model kits made of both the L10A and the L10B versions of the Mazda Cosmo, although kits of the L10A are rare.
I could not find any model-specific color charts for the Cosmo, so this is more of a list of colors than might have been applied.
As the Cosmo was hand-built I assume that it could be ordered in any of the colors Mazda had available, however most were delivered painted white.
Although car colors in the 60ies were mostly low-key grey-ish or off-whites (with a blue or green cast), Mazda did have some bold colors listed on its color charts.

The 60ies was the era of space exploration, so many things were named after astronomical phenomenae. The name "Cosmo" was derived from "cosmos" and quite a few Mazda paint color names listed below have an astronomical theme.
What would be more appropriate than painting a Cosmo model in a paint color with an astronomical name ?

Paints for plastic models

For a polystyrene or resin model kit it is usually best to apply a suitable primer base coat (e.g. Tamiya gray or white primer) and then apply a thin top coat of automotive paint, I've added all Motip/Dupli-Color Auto-Color matches I could find, as I get very good results using this paint on model cars.
I've provided some model paint alternatives just in case model paint is preferred, I plan to add more whenever I find good matches. Please note that these are close matches, rather than exact matches.

Lists by type and model year

The lists are ordered by type and by model year.
The cut-off between early and late models of the L10B is a bit arbitrary as changes were not tied to model years due to the small production numbers.
To a scale modeler, the main difference between the early and late L10Bs are the indicator lights on the front wings, which changed shape from round to rectangular.

Cosmo L10A/110S Export 1967-1968

The most popular colors for the L10A and 110S were Chamonix White (a pale shade of ivory) and Granada Red.
A batch of pre-production cars was painted silver with white roofs and those were often used for publicity pictures. I am not sure if any production cars were painted silver.
The most spectacular color for an L10A/110S must be Hailey Orange as can be seen on this picture found at silodrome.com. Do keep in mind that orange was not a popular choice in the 60ies as common rust primer was also bright orange, the car in the picture was delivered painted white and was painted period-correct Hailey Orange after being restored.

Cosmo L10B Early 1968-1970

The most popular color for the L10B was "white", but there were actually 6 shades of white to choose from !
With Chamonix White being discontinued in 1970, it looks like Aurora White and the bluish Swan White were the most commonly chosen shades.
