it is actually, color is not a very trustful method to determine cannabinoid concentrations usually, but in the case of pink there is an exception, pink means Δ8-THC,which indicates that there was probably moisture involved, or longer duration of applied heat, oxygen also has an impact, can you describe your steps?.

edit: no intention to say that this is bad, Δ8-THC is also psychoactive and very enjoyable personally, but it is slightly less psychoactive than Δ9.
