1P-LSD unwanted test result

[Meister_Eckhart]

Hi, 

First timer with this substance and the test. I've cut off a small corner of the 1P-LSD 100mic blotter and then tested it with the EZTEST. 

Result below are after 1 and after 2 days respectively. 
I am not sure what this indicates but clearly the result is not purple and it doesn't even seem to match any of the expected colour spectrum.

Has anyone had similar experiences? Your advice is welcome.
