In the juvenile bird the lightest colour n the sculpture would be white, the other colours are fairly accurate. Ive always struggled to create a white using my traditional techniques, unless I was to cold paint it. Which I dont like to do as it removes the metallic look, in which case it might as well be plastic.
The adult bird goes almost pure white whilst still retaining a hint of the dark markings on the wings
Ive since mounted it on a black marble base
