[scribus] Some clarifications regarding Pantone [was: making your own Pantone color list]

[Olivier Berten]

Well... according to you, pretty much none of the palettes provided with
Scribus are of any practical use... I wonder why they are there... CMYK
numbers aren't any closer to actual color if they aren't refered to a color
profile...

Talking about the Pantone ones, the X-Ref tool <
http://www.pantone.com/pages/pantone/color_xref.aspx> provides data in
L*a*b* , sRGB and (when applicable) CMYK, i.e. the same values as in
Adobe's palettes. So the only limitation is in Scribus which is unable to
deal with L*a*b* colors.

By the way, for the people using color management in Scribus, you could
configure SwatchBooker to use the same color profiles, and import these
same data ("Open from web") which would then be converted to the right RGB
values for your screen... Of course, there will still be some discrepancies
with the actual colors but I guess I don't need to teach you why ;-)
