Red manpower and red Cash numbers on main screen

[just_one_more_turn]

For manpower and cash at the bottom of the screen I am seeing them in red, what does this reflect? At first I thought it was a negative amount but now I see that I was mistaken.

I'm just in the process of learning the game and I wondered about that. Finally found the reference in the manual after a bit of searching. For economic resources, being in red means that they are expected to shrink next turn.

Thanks, somehow I also clicked in that area and it changed from showing red 100 and 200 and then showed -2 and 0 so that makes sense that per turn it was not increasing.
