[accessibleimage] Re: Color code

Hello Ed,

This code system sound very interesting. Since we all know that Braille =
labels/tags can be a tactile illustrators nightmare when it means =
fitting them on a specific format/medium. This could really reduce on =
the frustration when creating the documents.
Do you have a standard for the minimum distance apart the lines must be =
so the patterns can be identified. I have tried quick sketching samples =
of the primary colors and they are clear. But, since orange and purple =
are mirror images of each other, I wonder if the secondary colors will =
be as clear?
I definitely would like to read more when your publication is completed. =
Keep up the great work!

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 =BA while blue and yellow are =
represented by lines of 60 =BA and 120 =BA 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,
Lisa
