Bar chart columns colour based on DATA

Hi,

In our dashboard we have a bar chart visual which is based on sales. Our main items are mobile handsets of a specific brand. Our brand has different colours of handsets,  we would like to show the  handsets sales based on their colors  in the bar chart , i.e. for red colour handsets  the bar should in red colour like that.

kindly advise how to make this happen

regards,
