Chart Colors

I have a report that containts 2 pie graphs. I want to have each slice a
custom color but don't know how to do this. So far, the best way I've come
up with is to save a picture of the color (just a filled jpg from paint) and
use that to fill the pie section. However, the edges come out blurry and
distorted. Is there a way to do this via vba code? The chart names are [B]
and [T]. Thanks!
