E2 test to Blue

[evo_merseyside]

We EZ & E2 tested a triangle superman (double pressed).
The E1 gave the typical purple/black.
E2 (the liquid is yellow before contact), went green then to blue 3 seconds later, the blue was a medium blue, it did not change from this after 20 mins. Not the usual E2 result on MDMA.
Any ideas on the contents/what blue means?
Just for information: the pills felt like weak MDMA, but lasted a long time, although the euphoric effect dissapeared after 1.5hrs from coming up. Felt clean while peaking. No sleep & headache all of the following day. Closed eye visuals when trying to sleep.

Bumpity bump.
Hi Evo
I've had this exact same result on E2 with two pills I've tested in the last two weeks, one a crumbly rolex and the other a well-pressed mitsubishi, both in North Yorkshire. I assumed the green/blue was speed but I'm told they weren't speedy pills (I didn't drop either of them).
Also interested in an answer, clop

Can someone with that US dept. of justice pdf of reactions have a look into this? I've lost my cable internet connection and I have a dialup which I can only use in spurts because its on a business line. I'll ask someone from chem gen next time I talk to them as well.
