Yep, Hex value is: A6B1B0

Yep, Hex value is: 0D0D0D

Now that being said, will it look the same on screen as on print? Only
if your screen is calibrated using special applications. That's why
printers rely on color charts and not on screen colors for their final
output. Different RIPs will also output colors differently, so the only
way to be sure is to do a color corrected hardcopy for proofing. SVG
Print 1.2 is an extension of SVG to add printing industry vocabulary to
the standard SVG spec. The W3C gives this example as a way to use color
profiles with the current SVG spec:

<svg width="210mm" height="297mm"
    xmlns="http://www.w3.org/2000/svg" version="1.2" referenceDirection="backwards">
        <color-profile name="MyColors"
            <text x="50mm" y="85mm"
                font-family="MyCompanyLogoFont" font-size="12"
                color="rgb(255,12,13) icc-named-color(MyColors, logo_color)">
                MyCompany logo.

Hence any color from any color library can be used provided the profile is available to the SVG document.

As far as glyph positioning, goes, as the link I included demonstrates,
you would use a <tspan> element to apply a character specific styling or
positioning to get it in the right place. No need to break a line into
multiple elements.

While Inkscape may provide good SVG support, that's not what I'm
suggesting. I'm suggesting incorporating SVG like features into Scribus.
While I feel using the SVG syntax and file format would make this easier
and would make use of an existing standard and talent pool, I can
understand that it's not as simple as that and that it may be best to
just extend the current file format to incorporate as many of those
features as possible and where appropriate.
