Hi Kevin,

Yes, this is possible.

Here are the steps:

In the Dashboard, Displays, Layout tab go to Layout Model --> Edit

Choose Lightning on the left, and double click on the layout model, on the 
right.

Go to the color By tab.

Select the Color From Parameter sub tab.

Select the field you wish to color by (e.g., signal)

Enter the parameter ranges and the colors. (e.g., -50000,0 RED   0,50000 BLUE)

Let us know if you get this working, and please do not hesitate to write back 
if you are having trouble. This is somewhat involved so it is easy to get 
confused. (I had to ask Tom for help. Thanks Tom)
