So far I am getting 6+ permutations of Level # color (styles), just with File Open, of the COIA-CORE.step file.
Always 13 of them.

In Explorer, with MoI closed, or open, doing file open of COIA-CORE.step gives at least a couple of permutations.

With MoI open, doing file open of COIA-CORE gives a few more permutations.

I have seen the green style as Level 2, 3, 4, and 5.

ps, I do have a very pale blue/white style called Level 1, which was adopted several months ago. (From a Fusion import I recollect.)
