[accessibleimage] Re: Examples with color code

Wonderful and very interesting Lisa,

I do have a question about Black and White. In 6 point what would you
use in cell one since the single dots indicate a color already. Maybe a
full cell all dots?
Also can any of these combinations be confused as short form/contracted
words. Of course the reader would already be in a color context. So,
that may not be an concern.

I typically use a texture key or letter keys: yw (1,3,4,5,6 and 2,4,5,6)
=3D yellow, rd =3D red, bu =3D blue, pl =3D purple, gr =3D green, or =3D =
orange, bk
=3D black, and wh =3D white. But, with a system like you suggest
monochromatics definitely could come into play.

Subject: [accessibleimage] Examples with color code

Hi,
Sending some examples using the code
Best,
Lisa

Examples:
In 6 point Braille
Light yellow  would be cell 1 dot 1 and  cell 2 dot 3, dot 6 Dark red
would be cell 1 dot 2,  and cell 2 dot 5 , dot 6

In 8 point Braille
Very light yellow would be cell 1 dot 1 and cell 2 dot 1, dot 8 Very
dark red would be cell 1 dot 2 and cell 2 dot 5 dot 8


Color coding=20

This is a way to convey color information in an graphic where this is
desired.=20
The idea is to convey information, the idea is not a way of experiencing
color.=20
This would be useful where one wants to convey information but have a
limited amount of area.
The information is language independent. Therefore one does not need to
translate such things.

The idea is that the code uses two Braille cells to convey the
information. Two variations, 6 point Braille and 8 point Braille.
Each point  in the first cell has a designated color information.
For 6 point Braille the second cell includes black, white, intensity
information and a marker point.
In 8 point  Braille the second cell is just intensity information and a
marker point.
Two  cells are always used.=20
In 6 point Braille point 6 of the second cell is always used, as a
marker.
In 8 point Braille point 8 of the second cell is always used, as a
marker.

The intensity could also be decided from before using scales.
=20
with 6 point
First cell color primary and secondary color Point 1 is yellow point 2
is red point 3 is blue point 4 is purple point 5 is green point 6 is
orange

6 point
Second cell intensity
point 1 is white
point 2 is black
point 3 is light
point 4 is medium
point 5 is dark
point 6 is a marker, and always used

In 6 point Braille
Light yellow  would be cell 1 dot 1 and  cell 2 dot 3, dot 6 Dark red
would be cell 1 dot 2,  and cell 2 dot 5 , dot 6

In 8 point Braille
Very light yellow would be cell 1 dot 1 and cell 2 dot 1, dot 8 Very
dark red would be cell 1 dot 2 and cell 2 dot 5 dot 8


With 8 point Braille
First cell color primary and secondary

point 1 yellow
point 2 red
point 3 blue
point 4 white
point 5 purple
point 6 green
point 7 orange
point 8 black

8 point Braille
Second cell  intensity (shows grade of intensity, saturation) point 1
light point 2 darker point 3 more dark point 4 darker than point 5
darker than 4 point 6 darker than 5 point 7 darker than point 8 marker
point
