Very similar to the reply I just sent to Wei: you can create a custom attribute or property and assign the values to atoms or residues. Then you can color the structure (including atoms, ribbons, surfaces) by those values.
To create a custom attribute, you create a simple text file and then read it in using the Define Attribute tool (in menu under Tools... Structure Analysis) or the command "defattr". The attribute file format is described here, and some example files are linked:
Then you can do the coloring with the Render by Attribute tool (under Tools... Structure Analysis):
Besides colors, the values can be shown with sphere sizes or "worms". You can also show the values as labels, as mentioned in the reply to Wei:
I hope this helps,
