[accessibleimage] Re: Examples with color code

Hi Heidi,

A full cell is a very good idea.  At first I thought one could have
just one cell for those colors, cell 2 dots 1,6 for white and for black
cell 2 dots 2,6.
But then it probably is easier to have a 2 cell rule and then
a full cell sounds best. 

One can also use the system to say that there are various colors
in an area. Then it would be best to not add a dot in the 
second cell , except for the marker dot. Unless all the colors 
are of the similar degree of saturation. 
I think also instead of the word dark, darker etc should be 
replaced by saturation/intensity. Increase in number is an 
increase in  saturation / intensity.


Example

for an area with yellow, red and blue splotches
6 point
cell 1 dot 1, dot 2, dot 3 
cell 2 dot 6

8 point 
cell 1 dot 1, dot 2, dot 3 
cell 2 dot 8


for an area with bright yellow, bright  red and bright  blue splotches
6 point
cell 1 dot 1, dot 2, dot 3 
cell 2 dot 5, dot 6

8 point 
cell 1 dot 1, dot 2, dot 3 
cell 2 dot 6, dot 8

Pigment colors - 

Also an pigment mixing  rule if one wants to be more specific
with say reddish orange color.
For that points 1,2 in the second cell in both 6 point and 8 point would
be the sign
to show that the colors in the 1 cell are mixed or a color between them.
And the remaining
points in the second cell could be used to show intensity. 

That is in 6 point Braille either dots 3, or  4, or 5 in the second cell
show intensity when point 1,2 are used to
denote mixing .
 When  dot 1,2 in the second cell are used in 8 point Braille dots 3 or 4
or 5 or 6 or 7 show intensity.

In 6 point for a grey in the additive that is black and white together
then, with the first cell being 
full would be handy. So grey would be

6 point Braille
1 cell full
2 cell dot 2,3,6

but here this would represent a 50/50 mix of the two. (For a more varied 
representation of grey  one could back to the first rule
first cell full second cell dots 1, 3,6.)

8 point Braille
1 cell dot 4,8
2 cell dot 1,2,8



Cheers,
Lisa



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.

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
