Looks like another good press has been copied. Yellow marquis is methelone or a closely related chemical.Mine turned violently yellow with marquis. No purple whatsoever. Looks like there are fake Partyflocks in circulation. To be fair they look completely different to the real ones. Have signed up to pillreports and will get a report up in due course. Haven't felt the need to sign up thus far as have had a steady supply of legit beans. Gutted.
