QUESTION:
What does it mean that the first color-enhanced photographs will be
available by July 6?

ANSWER from Mike Malin on June 4, 1997:
This question really should go to someone associated with the Pathfinder
Project directly, and specifically with the IMP experiment.  As far as I
know, color images will be available with the first couple of days of
landing.  Since these are taken as a series of black and white images that
are then combined into color, and since the color filters cannot exactly
match the response of the eye, most of the color photographs will be
enhanced relative to what one would see by eye.

ANSWER from Guy Beutelschies on June 30, 1997:
Assuming that we get our High Gain Antenna working as expected, we should
get color pictures on July 4th.

We do have color calibration targets on the lander and our plan is to take
pictures of those (whose color we know extremely well) and then correct the
pictures of the Martian surface (whose color we don't know very well). These
corrected pictures may be what you are thinking of but those changes will be
small and probably only noticable to scientists.
