Why doesn't this work?

[Martin Vermeer]

RGBColor const X11RGBfromhex(string const & hexname)
{
    RGBColor col;
    istringstream is(STRCONV(hexname));
    char c;

    is >> c >> std::setbase(16) >> setfill('0')
    >> setw(2) >> col.r
    >> setw(2) >> col.g
    >> setw(2) >> col.b;

lyxerr << "string=" << hexname << endl;
lyxerr << "c=" << c << endl;
lyxerr << "col.r=" << col.r << endl;
lyxerr << "col.g=" << col.b << endl;
lyxerr << "col.b=" << col.g << endl;
    return col;
}

For hexname = "#ff6a88"

the first two digits should go to col.r, the next two to col.g and the
last two to col.b. Instead they all six go to col.r. What did I miss?

The character c is read correctly.

I have included iomanip.
