Hi,
I am aware of the availability of digital chips both of FS and Russian colors.
The fact is that the visualization of digital chips depends both on scanner settings, the monitor settings and the subjective interpretation, because it is impossible to see the monitor chip and a materially painted surface under the same light.
It has happened that I found the visualization of known colors of Colorserver very different from the impression that they made looking at the real FS catalogue that I have; I don't think that it's fault of the catalogue itself.
Both real planes and models are materially painted, and not with RGB colors; the digital media are only a way to communicate the color of a real plane, or a real chip, to modelers.
This media can distort the color, and create problems of interpretation.
Now, if one has a real FS catalogue, he can correct distortions; else, he can't, and is left to the subjective interpretation of a digital chip that could be distorted.
For example: this altered version of the same photo gives exactly the information of the supposedly right one, when it is compared to the real fs catalogue.
Besides, the perception changes if it is presented on a white, or a black, or a grey background.
In this example, people is already aware that it's always the same chip, but in other cases could be fooled by the contrast to the background.
Of course, lacking of a fs catalogue, one can always use any known chip as a reference, or even the cover of a publication, if it is included in the photo; but lacking of such reference, digital colors are indicative only.
Regards
Massimo
