New draft technique for Situation B in 1.3.2 and 1.3.4

I created a draft technique, Using Color and Pattern [1], for situation B 
in success criteria 1.3.2 and 1.3.4.  Situation B is, "Color is being used 
within an image to convey information."  I tried to use the ideas that 
Lisa sent to the list, although this general technique is fairly simple. 
In the example I specified that black should be used for the pattern.  I 
assume that the use of black is considered available in a non-color 
dependent manner?  If I didn't specify black I was afraid that the 
technique could be met by creating the cross hatching in a bar chart using 
a color and thus would still not be accessible to some. 
Please review. Thanks.
