[accessibleimage] Re: Color code

Lisa, here are more details on the Tactile Vision Color Code System.

The basis of this system was taken from the theory of color which states
that any color can be represented by mixing the three primary colors: red,
blue and yellow.  It follows that the hue of any color depends on the
relative proportion of these three components. In this method of color
presentation for the blind, it is proposed that each primary color be
represented by a raised line. According to this convention, red is
represented by a horizontal line of 0 º while blue and yellow are
represented by lines of 60 º and 120 º respectively. It follows that green
will be represented by superimposed yellow and blue lines, purple by red and
yellow lines and black by all three.

The system for color representation is simple in that it is based on three
basic symbols.  It can be learned, in its simplest form, by a child or
extended to more advanced levels to be used by scientists, printers and
artists depending on their knowledge of, or interest in, color .

The strength of the Tactile Vision Color System is its universality. In its
raised print version, it can be used by individuals who are blind or those
who have other disabilities. However, in flat print format, it is suitable
for use by sighted individuals including those who are color blind.

It should be noted that I have chosen to discuss the primary colors, red,
blue and yellow which are those commonly accepted and used on a daily basis
by most individuals including artists. The color coding system could be
specifically tailored for the printing and copying industry where the
primary colors are identified to be magenta, cyan and yellow instead of red,
blue and yellow.

As I mentioned earlier, I am preparing a comprehensive publication and will
make it available as soon as it is complete.

Ed, that sounds very interesting.
It would be really nice to hear more
about it.
Best,
