What could be seen in the previous scan of the 5c Banco Nacional were the yellow/orange fibers!

In the last two years I have discovered that specific colours of fibers to be found in the paper used for postage stamps belong to different paper mills!

The first type I met was the green fiber in the Wiggins Teape papers with the parallel watermark and an asymmetrical paper mesh - the so-called rayado vertical; then the blue fibers in the 1922 Dutch paper used for the 1921 Postal Congress and the 3c José de San Martin - all with parallel watermark and a symmetrical paper mesh.

Quite recently the brown fibers in the Wiggins Teape papers of 1936-1938 - parallel watermark and a symmetrical paper mesh with density 30/20; followed by the same type of fibers again in Wiggins Teape paper this time with a density of 24/22 - the so-called Tela - during the 1941-1945 period!

And right now, the yellow / orange fibers of the Mate Lustroso! A paper of unknown origin with an orthogonal watermark and a symmetrical paper mesh used during the 1940-1941 period!

So, for you Rein, which would be the colour code up to now??
Here's an excerpt of what you mentioned:
I'm not sure about the years.

Blue >> Dutch paper (paper Mill name??) ...... Date interval : ??
Green >> English paper (Wiggins Teape) .......... Date interval : ??
Black >> English paper (Wiggins Teape) .......... Date interval : ??
Brown >> English paper (Wiggins Teape) .......... Date interval : ??
Yellow >> Unknow (on "mate lustroso" i.e.) ......... Date interval : ??
Orange >> Unknow (on "mate lustroso" i.e.) ......... Date interval : ??

Anything else??
