Cegli that pdf you posted earlier says MXE should change from Yellow > Green > Red, I've wondered if different isomers might affect the reagent differently?AshiataShiemash says GC/MS verified samples are red/brown. The official dancesafe leaflet says MXE turns green...
I've done more bunch more research and emailed dancesafe, and retested and I think I have the answer now. It looks like MXE's color differs with Mecke, depending on how much powder you use. This description from http://www.ecstasydata.org/view.php?id=2678 with a GC/MS verified sample sums it up perfectly:
Very interesting. Also interesting is that some of the results don't match with the original Dutch article (and I can't figure out how to register so I can edit it).I think the following link also fits pretty well in this topic;
Its a page that show's a nice table with a bunch of different marquis test results, including pictures..

It's supposed to be! Methylone is bright yellow according to the only gc/ms-confirmed samples I have seen, but it would appear that DanceSafe, EZ Test, DHP, D-F, and the Nexus all have similar results, so either everyone is mixed up.. or the DEA is. Though to be fair, I haven't used EZ's modified Mecke yet.Hey guys - I have some methylone - its pink/clear
i got the tests and was wondering your opinions why the mecke is so bright yellow instead of brownish..

EZ For mCPP and Phenylpiperazines. I got a positive reaction for mCPP/TfMPP.
Cuts? Whatup? I'm a bit sketched. Had I not had the EZ Test I would have assumed I was golden but now I am curious.
What colour does 4-FA test up as on a Mandelin Reagent?

On that link you'll find a result for 3-MeO-PCP for the Marquis test, and it matches your description of the two batches, but perhaps compare your results with their photo.
But you only need a slight impurity to change to colour reaction, especially since 3-MeO-PCP colours so weak by it's self! So it will be difficult to draw any serious conclusions from this result.
Here are my results from testing 3-meo-PCP with marquis and mandelin. There was no real reaction with both of them. Just a small yellow tinge but i presume it was from contamination or synthesis byproduct. Sample was also submitted for GC/MS so i will update you when i get the results.

Heres a couple more, not sure how valuable they are but anyways, all three are in the same layout left to right : Marquis, Mecke, Simons A&B
