Custom Coloring multiple measures in Stacked Bar Chart

[Beginner]

Hi,

I have 4 measures, each of which I would like to apply a custom RGB color in my stacked bar chart. 

My four measures are the following:

Sum([stream 1])

sum([stream 2])

sum([stream 3])

sum ([stream 4])

What custom expression would I put under the color section to do this?

Thanks

The easiest way is to create your measures as Master items. You can then assign separate colors to these new master items. When you use these master measures as measures in your chart they will automatically have to color you assigned to them when you created them as master items.
