How to change the color of the each bar measure in Qlik Bar chart using expression

[kishore3k]

Hi,

Is there way to change the color of the each measure in qlik default bar chart using expression. I know it is possible using master measure where we can select the color. 

I am thinking of the changing the color based on selection.

i.e as you can see below we have one dimension and three measures. I want to set custom(RGB or HEXcode)colors based on expression and selection. 

Please let me know if you have any ideas.
