I got the Hadar when it came out. It's mostly languished in a drawer since then. But I didn't have any problems with the colors, blue or otherwise. And I still don't, though I prefer louder, less greyed shades myself. I sort of hated the intergalactic mutant flowers the deck took from the Dodal. Probably that wouldn't be such a problem for me today.
This thread prompted me to open my box of the newer edition, which I'd been saving as a backup or gift. One difference with the newer deck, not yet mentioned in this thread, is that the pips, twos through tens, have a Roman numeral at one end, indicating the top of the card. If someone is of the "the odd sword points down" persuasion, this might be an annoyance. It seems like a funny change to make. Kris Hadar had already designed the cards so that you could tell which end was up without having to mark the cards. That was encoded in which bits were red or blue, and which way the roses pointed on the coins and whether the swords were odd or even numbered. Knowing the system was fun, in an "I know the secret handshake" sort of a way.
