I would hope, that when the Kroma hits full production, that they are available in 'other' colours, rather than the red and blue combo that seems to be on the cards at the moment.
I know what blue light can be used for, but I just don't need it! I'm in the military, and I'd find either NVG green, or UV much more useful than blue.
Red for 'Emergency Stop", NVG green for all clear or night ops, and 2 level white light.
My SF L1 is one of my most used lights, I really appreciate the low light/long runtime option for reading at night, with the option of more light if needed, but I can't imagine liking it if it only had a coloured LED, such as red or blue- much less useful for me.
The A2 Aviator is available in a spread of LED colours, so hopefully the Kroma R&D team will pull something out of the bag.
