Try Override color in view, gemetry color works for Dynamo enviroment only!!

Personally i don’t use Import Instance, but if it works for you use it, i use FamilyType Bygeometry, and then Family Instance By point, i have much more control, i let yu the link for the topic, I hope this helps you my lady!!
