"warning" colors on object

[cruisemon 0]

I found a reference to red areas on  the graphic meaning that there were potential/guaranteed overhang print problems.  I have one with blue areas on the object image and can't find a reference to tell me what it means.  I searched the forum and apparently don't know the correct search term to input.  Could someone point me to a resource with the answer or tell me what the blue areas mean?

Hi, could you post a screenshot of that?

If you mean the outline around the yellow object - that's just that the outline
