[scribus] bg colors missing / scribus-ng 1.3.3.6

[stu seven]

After downloading and compiling scribus-ng 6-8 months ago, I
was overjoyed to see it available with latest stable debian release,
and quickly erased my old directory, together with fixes :-)

Now I have this problem again... that scribus-ng supports only
a small subset of background colors, instead of the 100 or so
which other scriubii have... so... my question is - what file(s) do
I need to make more bg-colors available... or... is there such a file
for scribus-ng yet ?

thanks
