Ok, I've got the dunwich horror expansion and realize for some reason the color icons on lost carcosa are yellow and...purple?

Looking thru the cards it would appear that it's supposed to be blue and yellow, but is this actually the case? Or are there actually purple cards?

yeah, my copy has that too, it's a misprint. Blue and yellow is correct.

This f****ing fake blue is everywhere in FFG games, I don't understand why they didn't yell like crazy against the printing company who makes their games, because ****, they suck (if they do it themselves, well, sorry FFG, it still sucks). In one card I'm not saying anything. In a hundred cards, this is frustrating. In a whole game, this becomes annoying. In several games, man I may nuke FFG's warehouse ! Descent is the same, and I'm pretty sure I saw that colour somewhere else too... might be in Twilight, I don't know, I forgot. I named it then : the blue colour out of FFG's space ! End of complaint... (I can't be always cheerful, can I)

It's not the printer's fault. The blue that was used in the the base board and the blue that was used in Dunwich and Kingsport were just different swatches in the files they sent to the printer. It's true that the revised base board should have been updated with the newer blue, but what can you do.
