Dark maroon-black vs inky-blue-black result

[Ringfinger]

A few people on here have sworn that the old skool MDMA used to test inky-blue to black, which is what distinguished them from the dark-maroon to black color that most Euro MDMA tests for now.

Personally, I don't buy it. But I didn't know anything about MDMA back in the 90s.

I suspect that the people who say that are mixing up the Marquis with the Mecke, which does show an inky blue look.

Take a look at these pics:

It is totally possible that they are mixing up the two reagents. The Marquis reagent has been around for a very long time, and I never remember it being blue. Why would they change the reaction color when Marquis is used for testing many different substances?
