@fxamoneymaker Check available buffers if you have the source code of the indicator. usually there is at least 1 buffer that mybe is not visual but indicates the trend (which then will be painted in different color). That's how I do so.

Of course you need some basic knowledge to do so.
In case you don't have the sources, there might be a way to read the color from a chart object, but that's a different story and not what I use in general.
