Hi, Christoph!

Here is it. But, as there's not a "defineColorAsRGB()" function in
Scripter, the RGB colors are created as CMYK anyway, although have RGB
names.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import sys

try:
    import scribus
except ImportError,err:
    print "This Python script is written for the Scribus scripting
interface."
    print "It can only be run from within Scribus."
    sys.exit(1)

def main(argv):
    """Translate imported RGB colors to CMYK colors."""
    if scribus.haveDoc():
        colorsList = scribus.getColorNames()
        newColorName = ""
        for colorName in colorsList:
            if colorName.find("From") == 0:
                if not scribus.isSpotColor(colorName):
                    colorCode = colorName.split("#")[1]
                    if len(colorCode) > 6:
                        cmyk = scribus.getColor(colorName)
                        c = cmyk[0]
