You can try using an rgbf texture.

If you can't get that to work properly, have a look at "projected_through"
for light sources, i.e., duplicate the lights but with the colour you want
to result from the shade and have them projected throught the shade.

One problem that you will need to address either way is that the lighting
from the shade shouldn't produce as sharp of shadows as from the bulb
directly as well as dimming/colouring it.  Using projected_through, you can
make the shade light larger (i.e. approximately the size of the shade) to
simulate this.
