The "colorspace" package provides a wide range of colors that - when 
printed on a grayscale printer - still preserve an increasing/decreasing 
gray palette.

To explore these, see choose_palette() in "colorspace" which opens a GUI, 
let's you play around with the palettes, see them in example displays, and 
also let's you collapse them to gray colorse (option: desaturate).

Furtheremore, you can explore the effects of different types of color 
blindness (provided that the "dichromat" package is installed).

Best,
