[Framers] cross-ref color for printed and electronic documents

[Carol J. Elkins]

Does anyone know if there is a specific color to choose to color 
cross-references in Framemaker so that, when printed in black and 
white from the resulting PDF, the color is not significantly 
different than surrounding black text? My thought is to provide 
customers who purchase a product's PDF the added value of colored 
cross-references while ensuring that customers who purchase a B&W 
hardcopy are not distracted by a change in the crossferences' look. 
Because there are a zillion different cross-ref formats, I do not 
wish to create a separate set of formats for PDF and hardcopy.
