Hi all, I understand that the default color on the Petrel 3 is green to reduce battery consumption (white can use as much as 3 times more power than green to visualize). Is this a default that can be changed to another color or cannot be changed? I am asking because I am considering switching to a Petrel 3 but I am used to white main color on all my Shearwater computers (Perdix 2, Teric, NERD 2). I don't care about higher battery consumption as I am sure you could still do a good number of hours on a lithium battery with white font (otherwise how could the Petrel 2 do it?).
