Saurus and skink units used to be blue with faction specific markings. In the latest patch this base coloration is more faction oriented, but the LOD imposter models are all still blue. I'm talking about the 'super low poly' skink_super_imposter.rigidmodel that is used for all regular saurus and skinks units when viewed from extreme distance.
Here is Cult of Sotek, who are now yellow, but still blue at a distance:https://drive.google.com/open?id=1mH8tKdnAJC4pCJS1XgOufAowFumIRL1e
