Elliptical light inside cloud formation moving south at a slow speed.

Looked north and noticed an elliptical star/ galaxy type light inside what appeared to be a cloud- it was slowly moving south/southwest from me. Watched for a minute then filmed a video. Went inside and got someone else to come look at it and watched it continue to move south until it was past our view and below the tree line. It appeared to have changed shape and color from a blue to more an orange color once I returned outside.
