This may be a state issue, perhaps you need to enable lighting
or some such thing for the string. Look at the setGstate method,
and check the material color mode, geometry color attributes may

Look at pfdLoadFont, you have a large choice of styles most
of which eliminate the 3D stuff you probably currently use
PFDFONT_EXTRUDED. You can even use textured quads.
