From what I can tell it is both. For example a Heavier Tank's main cannon attack should be red when aimed at a the Big Bada Boom because of the explosive damage resistance regardless of the range. And normally when the same attack is aimed at a unit (who isn't elite) it is yellow/orange/red depending on the range.

That's based on my personal experience so I may be wrong on the formalities.
