I have a father, a brother, and a son who
are red-green color blind. We didn’t start looking for this until
we got our first color TV many years ago. Dad was in charge of the new,
expensive device, and turned the knobs on it until he got the color just right –
it was totally blue and pink. He thought it was fine, and when the kids
changed it to include blues and greens, he couldn’t tell the
difference. We got the hint on my brother when he got old enough to
select his own clothes in the morning, and chose some very interesting outfits. A red-green color blind judge would not be
able to tell the difference between dark reds, purples, rust, brown, and dark
orange colors. It makes a difference in the determination of clear or
muddy color, and in the comparison with other clones, and the description of
the color – all important in the judging process. li’l frog From:
[EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Stanley Over the years I have encountered
some half dozen red-green colour-blind adult males while teaching geological
map interpretation. Two of them (both of post middle-age) were completely
unaware that they were colour-blind at all until they found difficulty in
discriminating between very subtly different colours on maps
and, later, checked themselves out using Ishihara-type colour dot-pattern
charts ***. As I understand it, there are degrees of (or variations in)
colour blindness. Some are but slightly affected, others more so. How then
would it be possible, desirable, fair, advantageous or even legal to have
a ruling preventing a colour-blind person from orchid judging? Am I correct in
my belief that almost all colour-blindness is not 'grey scale' . Maybe a colour blind member of this
forum could make his views known. I believe that the phenomenon is
mainly sex-linked and that female colour blindness is very rare, but
again,maybe an appropriate expert member could put me right? John Stanley |
