An image by Oskar Bertrand from 2004 inspired me to render theses

looking up the official colors.

Here are some other materials: matte, glossy, and crystal.

Very nice indeed. I didn't even know that there were /Olympic/ colors! ;-)

I see that they are using the heraldic names, and there are two that are 
incorrect.

«vert» should be «sinople» and means green, and «gules» should be 
«gueule» and stand for red.

My cent:

Until the early fourteenth century, the term sinople was used in French
literature as a poetic designation of the color red. This word derived from
sinope, sinopis, Latin words that in classical antiquity usually referred to
red, in allusion to a kind of much appreciated red ocher that was extracted in
Cappadocia and exported from the port of Sinope, in Anatolia. Even after its
adoption by heraldry with the meaning of "green," Sinople retained its literary
meaning of "red" for about two more centuries.

The heraldic names were my idea, not theirs.  (I'm sure that the IOC 
knows nothing of POV-Ray SDL.)  I used them because the colors were said 
to represent those of the flags of the participant countries.

I used the only names I have ever seen for heraldic colors.

else than heraldric green.

Metals :
Silver = white
Gold = yellow

Noble colours :
Sable = black
Gueule = red
Azure = blue
Sinople = green

Lesser colours or semi-metals :
Tan = tan or beige
Carne = pink

Furs :
Vair, contre-vair and hermine

There are several more that I don't remember.

And for English speaker (of Heraldry), you were correct.

Gueules (fr) = Gules (en) = red
Sinople (fr) = Vert (en) = green

As far as heraldic is concerned, the name is about the concept (there is
no right srgb values, and no wrong either as long as it can be recognised)

That's totally different of vexillology (about flags), where each colour
in a flag is specific.
If you take the "blue" of France, Luxembourg, Netherlands, it is NOT the
same.
And they are also painful about the ratio of partition (and globally).
(including the usage of flags at sea or in land)
Compare the 10:19 of USA's flag (nearly twice as long as high) to the
ratio of Switzerland (1:1 a square!)

Inland France is equal strips, on 2:3 ratio.
But navy of France use 30:33:37 proportions.

That last one is the proportional area of each colours in %.
Red for 30% of the length, then white for 33% and blue for the last 37%. 
This makes all colours visually equal on a flag in normal low wind 
conditions.

The sun moved behind a cloud.  I had to increase the exposure and the 
white point temperature to get a good color balance.  No light probe was 
used; my prefab checkered plane environment can increase the light 
source intensity and sky finish emission.

Oh, BTW, if you shoot photons from behind an opaque cloud, trying to 
reload the consequently nonexistent photon file will cause a parse error.
