Is it possible to customize 'Color Scheme' for chart?

[mak]

I'm using Stacked Column Chart.

This output has to be printed in black and white.

So it has to be easy to judge what color means what column.

 

I thought it's possible to chose color for each column but I cannot find how.

 

Is it possible to do so?

 

If not, what color scheme pattern is the best for black and white only prints?
