Description
As a scientist I'm often confronted with the need to choose greyscale safe colors in my document. Currently, I use a crude ghostscript line to convert my PDF to greyscale to check for this. It would be great, if evince would allow a greyscale rendering (similar to inverted colors) this could be done within evince.
