There are some experimental drivers that support color,
applied to the Type 1 fonts that come with Xy-pic.

You can get them from:
http://www-texdev.ics.mq.edu.au/WARM/

Explore that site, for examples of labelling mathematical
graphics using Xy-pic. The methods work for all flavours
of TeX and LaTeX.

The experimental drivers do most of what you want in practice.
As yet, they do not do direct construction of lines and curves
in PDF, but construct such graphics using font pieces.

However, the results are remarkably smooth, since the PDF reader
applies anti-aliasing to the (fully hinted) fonts.
Indeed, on-screen the results from this can look better than
using Xy-pic with \xyoption{ps} (for PostScript graphics) then
producing a PDF with Adobe's distiller.

Thanks.
I hope you'll like the PDF capabilities as well.
