I agree simple is better than complicated, which is why I use either pdftex
or luatex instead of any form of LaTeX. The math formulas are identical.
There was no need to add the complexities of LaTeX to Scribus, but most
people are more famiiliar with LaTeX which is probably why it was chosen.
I have been working with TeX (various formats) for nearly 2 decades now.
I only use pdflatex when I need the various special facilities of the
Memoir class. That class is not relevant to Scribus.

The TeX file pdfcolor.tex defines 68 colors in CMYK form. (More could be
added by the user of course).
In that file each color is defined in two lines:

\def\cmykGreenYellow{0.15 0 0.69 0}
\def\GreenYellow{\pdfsetcolor{\cmykGreenYellow}}

Note that the range in TeX for a base color is 0 to 1, not 0 to 100
as in Scribus.

But the user need only know the name "GreenYellow"

You can use the file in e.g., pdftex thus:
\input pdfcolor.tex

Then in pdftex any passage of text can be enclosed in brackets and it will
appear in a designated color thus:
{\GreenYellow here is some text}

Now that is simple. And that is CMYK, TeX style.
