Our links are blue and red. Can you confirm that these really are
indistinguishable to someone with red-green colorblindness?

I would really like to know if this is based on actual experience (eg,
you are colorblind or a colorblind person has reported to you that they
are in fact not distinguishable) or if it's speculation. Without hard
data it's going to be very difficult to just come up with a change.
