Your reply starts by mentioning color palettes based on Swiss design, but is that the case here? It seems colors individually are not part of ITS, but how they are used (and therefore all colors can be used on it, as long as properties of this design philosophy are observed).

"The following points must be considered whenever it is planned to use colour: the effect on the viewer, its usability in the various advertising media and the technical possibilities of reproduction.

The sparing, but methodical and logical use of colour has a more telling effect than a combination of many different colours. If colour is used, it should be plainly visible and the reasons for its use immediately apparent."

- Josef Müller-Brockmann The Graphic Artist and His Design Problems (1961)

which is a good book even now, it's a practical guide with plenty of examples, so you can get a good look inside his head, even if you don't necessarily agree with everything he wrote.

The Swiss style seems to have influenced the covers of a lot of old sci-fi books, so I mentally associate these kinds of color schemes with faded old paper and sitting indoors on a rainy afternoon.
