Dear all, 

I became recently aware of the problem of color blindness:

"Colour (color) blindness (colour vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world. In Britain this means that there are approximately 2.7 million colour blind people (about 4.5% of the entire population), most of whom are male."

This made me think how I can publish charts that are easy to read for colourblind people. I realised that currently it is not easy to apply an automatic pattern to a chart. 

By pattern I mean an example like this: http://support.sas.com/kb/45/addl/fusion_45663_1_fillpatterns1.png

Instead I have to modify the colour for each of the individual data ranges. 

I would like to hear your opinion whether we could imagine an option that automatically applies a pattern design to an entire chart. 

Thanks,

Robert
