I am sure there are cases where you might want your image to maintain its colour e.g. logos, legends, usability or purely for aesthetic reasons. When applying the stereographic options the colours available are reduced which is correct and part of the process. However 2D images which can't be converted to stereographic are still given this reduction of colour. In a future version of Jmol would it be possible to give an option to prevent this from happening?
The attached image demonstrates the reduction of colour when the "Red + Cyan Glasses" option is selected.
