It's a fascinating article, but when I browse the pictures at the BBC site, the trends in changing colors just don't feel right. While black and white are 'colors' to a painter, they are not colors found in the spectrum. Maybe the real underlying reason for changes in the spectrum are changes in the use of black and white??? Conversion of black and white pixels into the spectrum is likely not very intuitive. Old white paint, for example, often has a faded tan look, which might be converted to orange in the spectrum. In newer paintings, white often has a slight blueish cast.
