Marquis/Mecke - is this 2c-e?

[4Progess]

I received what I believe is 2c-e from a reputable vendor. I took the marquis and mecke test, but they seem to vary slightly from the results online.

Marquis: slight fizz, immediate orange to darker orange to dark murky brown over 5 minutes
Mecke: Dark green (mostly green)

I've attached photos of the results.

Please share your thoughts.

I always thought marquis should turn yellow/greenish colour.

NO - marquis will give you a green reaction to most of the 2c's !
