Any updates?

Thank you for interest! These elements were not imported with Dynamo. I think that the .rvt file was a template without much cleaning in material library. These are just some leftovers ;p HINT: I have figured out, that after PURGE (without any filtering) the problem does not exist after IFC export. I've tried to purge one type of information at once and repeat the export each time, but I didn't come to any conclusions :(

Attached you'll find files. Problem persists in all viewers. P.S.: BIM Vision developer reported that mistakes on their side have been corrected.

Thank you for the answer! ...hmm. I checked this particular file in BIM Vision only. It looks like it's displayed correctly in Tekla BIM Sight and Solibri. I've also checked the original file - it is wrongly displayed in BIM Vision only... That makes me look bad, doesn't it? ;p So there actually is some problem on the viewer side. But... My assumptions were made on a different model with similar problem. All slabs marked "x" have the same material. They have different colours though. Screenshots...

And here comes the strange part. When I'm exporting only those 2 elements mentioned above, their colour is OK - according to the setting. I've exported 4 elements which combination gives wrong results. (They are not the ones mentioned in the first post). There is one element with material "Filling material" and 3 elements with "Concrete" assigned. Only 1 "Concrete" element has the right colour. The rest of the elements have the colour of "Filling material" material.

Hello, Revit 2018.2 Elements in my IFC model appear in different colours despite having the same material assigned. I've encountered this problem recently when exporting from Revit to IFC 2x3. (I won't even start with what happens to the same file when exporting to IFC 4 :D ). My IFC viewer is BIM Vision. I've talked with many friends in the industry, noone has any idea, so consider me as representing a few of us having the same problem ;p What I've already ruled out: 1. IFC Viewer is the problem...
