Draft general technique for SC 1.3.2 and 1.3.4

Here is a draft general technique that I *think* will work for both of
the SC about color (1.3.2 and 1.3.4). A version in .rtf format is
attached.

We'll discuss on our Wednesday call.


Ensuring that color-encoded information is also available in text
Description
Color is an important tool for conveying information. To ensure
accessibility, provide the information in text.
Examples
Example 1: A color-coded schedule
The schedule for sessions at a technology conference is organized into
three tracks. Sessions for Track 1 are displayed over a blue background.
Sessions in Track 2 are displayed over a yellow background. Sessions in
Track 3 are displayed on a green background. After the name of each
session is a  code identifying the track in text: T1 for Track 1, T2 for
Track 2, and T3 for Track 3.


Example 2:A color-coded schedule with icons
The schedule for sessions at a technology conference is organized into
three tracks. Next to the title of each session is a colored icon
showing what track it belongs to: blue icons represent track 1, yellow
icons represent Track 2, and green icons represent Track 3. Each icon is
associated with a text alternative reading "Track 1," "Track 2," or
"Track 3," as appropriate.

Example 3: A table showing the conference schedule
The schedule for sessions at a technology conference is organized into
three tracks. The schedule for each day is shown in a data table with
headers for Time, Title, and Track . Sessions for Track 1 are displayed
over a blue background. Sessions in Track 2 are displayed over a yellow
background. Sessions in Track 3 are displayed on a green background. 

Tests
1.	Determine if color is used to convey information (requires
manual review)
a.	For each color-encoded instance, determine 
i.	If the color can be programmatically determined
1.	if "No," then determine if the information is available in a way
that does not depend on color

"Good design is accessible design."
