In your color display, set global visibility to off, and then turn on just top pins and pastemask_top.
On the options tab select class Pin, and subclass Pastemask top.
Make sure that pin and pastemask are different colors.
You will now see the pin color for any padstack that does not have top pastemask.
This procedure can then be repeated for the bottom.
I have some Skill code to do this check. Let me know if you're interested.
