A customer in Holland sent me this;
I see at least 6.
He sent me this photo as a result of a dialogue we were having about which paints to use and whose colours are accurate.
The demise of Floquil has had a certain impact on modelers options. Fortunately there are still lots of options out there.
I don't use acrylics. I've had too many issues with them. And as regular readers know, I'm done with Trucolor. But even with those limitations I have plenty of options.
I use a lot of Scalecoat. They have 6 basic brown/reds that I can use to mix and match to get the tones I'm after. The Testors Model Masters enamels are an excellent option as well. While created mostly for military modelers, there's lots of colours to work with.
Now for our friends in Europe, Scalecoat is not an option. Shipping issues preclude getting it overseas. Canada has a similar issue. But there are always lots of options. Humbrol comes to mind immediately.
And for those fine gentleman who created those extensive colour matching lists for the various railroads; thanks but as the photo indicates, there's lots of variability.
