Yes: PhotoShop.  Since those images have already been "cooked" from 3 of the
original bands, it is a painful process of: fuzzy select, select by color,
shift hue, color balance, adjust curves and levels.  I've done it many
times.

What you'd IDEALLY want is to start from is the original bands.  But all of
the Zulu site is something cooked up from, what looks like,
red-green-infrared.

The task is something like being given a big pile of turkey sandwiches, and
deciding you want a whole roast turkey instead.  You get to take all that
turkey and smoosh it together trying to create the desired results, when it
would be so much easier just to start with the raw turkey.
