Third order from anycubic, previous two orders had “random” selection consisting of 3 black and 2 grey rolls of PLA. This order was for a colour pack detailed on the page down to the rgb colour values. The page states PLA may be substituted for other types (not colours) of filament. When it arrived, only two of the colours were as ordered, one replaced with a colour almost identical to another in the pack and the other with - you guessed it - more black PLA.
