Thanks, MPB, for your input. I am happy to report having heard from a
number of similarly sensitive teachers seeking to reach kids who may be
touched by disease. I wanted to comment on your mention of a "mustard
colored" person. Interestingly (and I assume this may be true of a number
of illnesses), I observed that my mother's choice of colors drastically
changed as her cancer advanced. Whereas she once preferred bright, clear
colors she wound up choosing mustard, olive & other drab & muddied colors.
It would be interesting to observe the artwork of child or adult cancer
patients over time to see if this holds true for large populations.
