My understanding is that the boxes are visible only on the screen. They
are not printed. The PDF creator can choose the color of the boxes, but
I don't think it requires the color package if no actual text is
colored. Coloring links, if I remember correctly, colors the text and
turns off the border (sets the lines to zero thickness). This causes the
color to be printed.

The problem (in my opinion) is that there is no method present in
AcroRead to highlight links _only_ on screen except boxing them. I am
not sure about other viewing programs. (GSview will display PS files and
provide linking within the document; some dvi viewers will do the same
with dvi files.)
