Does MDMA turn Mecke green to purple or green to blue?

[Zeknichov]

I can't seem to find a definitive answer, maybe because everyone's idea of what is blue and what is purple is different. I've seen pics that make it seem blue rather than purple. I recently tested an unknown substance and it went green to the following color. Is this what its supposed to look like? This is the best pic I could come up with, there's clearly a hint of purple but absolutely 0 blue. If it was blue it was only for a split second as it went from green to this nearly instantly:

Sometimes it flashes green, then it will go to purple or black. Not blue, but black. Sometimes it can seem a bit blue I guess...

This looks OK, if a marquis is testing good too

It just seems odd that the same drug can have completely different results. The color above looks nothing like the blueish-black in the topic here:

All the mecke kits I used turned green ---> DARK navy blue (looks black in dim light)

Under really good lighting, it typically has a very slight blue tint to the black, if you can imagine.
