Ooooook, this is really random. You know, guys? I think that Lego could have used another color instead of the dark grey. If you noticed, they have used Krana colors already appeared as masks. So, let's list EVERY mask color: Brown - NOT APPEARED Tan - Pahrak Va Burnt Orange - NOT APPEARED Black - Nuhvok Va Dark Grey - Actual Lehvak Va Purple - Gahlok Va Trans-Blue/Dark Blue - NOT APPEARED Light Blue - Kohrak Blue - Tahnok Red - Lehvak Orange - Gahlok Yellow - Tahnok Va Green - Pahrak Lime - Nuhvok Teal - NOT APPEARED White - Kohrak Va Light Grey - NOT APPEARED Sand Blue - NOT APPEARED Ok, so... Six colors aren't used, seven with the Dark Grey... Dark Grey: Good choice for me, but there was a better one. Burnt Orange/Sand Blue/Light Grey/Brown/Trans-Blue: To be honest, these colors don't really work with the air ambience... Maybe the brown for the logs... So, of course, one color is available... The one that I probably find the best for the set... TEAL. Oh yes, teal. This color already appeared in Matoran Kongu and Tarakava. The could've done a lime Krana bag like Kohrak Va and Nuhvok Va (they have light grey and dark grey Krana bags because their krana were white and black) and used the Teal Krana. I'm already imaging those... THEY COULD HAVE BEEN REALLY COOL! Do you prefer the Dark Grey? Or the teal? Or another color?
