QUESTION:
I was wondering if it would be possible to create a color sample based on
data from Mars. I'm researching using spectrophtometry to formulate material
to match skin colour for facial prosthetics. If you provided me with
spectral reflectance in the range of 400 to 700 nm at 10 mn increments I
could give it a try.

ANSWER from Bruce Jakosky on October 16, 1997:
This information is available in the published literature.  To get started,
try the chapter on martian spectroscopy in the book MARS, edited by H.H.
Kieffer et al. and published by Univ. of Arizona Press, 1992.
