Fetch the moustache and eyebrows and Join them (Arrange -- Join). Make a duplicate and apply the same red-green conical fill. Convert the colored duplicate features to bitmap, and repeat the SL-Blur process using a setting of 6. Paste the colored features back into Xara and position them over the face. Ah, there is a white background you say! No problem, apply a Stained Glass Transparency, amount 0% to the bitmap. Stained Glass Transparency makes the white invisible while retaining all the saturation and intensity of the other colors (as long as the bitmap is over a white background). Place the non-bitmap moustache and eyebrows over the bitmap, and change the fill to white and the outline to none.
