I have decided that I am obviously going colour blind. The photos on the balcony alongside Sophie make her coat look dark blue rather than black. Trick of the light?
This is all about the science of light refraction! The material of Catherine's outfit is reflecting more light than that of Sophie's and so appears lighter. Now, I believe that the scientists among us will confirm this, but of all the colours of the spectrum, blue is the least easily absorbed colour (and thus the most easily reflected) and so the coat appears to have a blue hue about it.
The same principal can be seen when washing your whites whiter than white - manufacturers of washing powder add tiny grains of blue dye to the white powder which make your white linens etc appear bluey-white. A blue-white is generally seen to be whiter than...erm...white.
