If you set budget limit for expense category it turns gray. During the month it would gradually fill – the more you spent, the higher color level would be.
Filling’s color show you whether you’re going to be ok with your spending budget this period:
Green – means that you spend much less than could be, according to your expense limit.
Yellow – means that you spend in ok or a little higher speed than you should.
Red – means that you spend a lot and are going to hit the expense limit soon or already spent more than limit.
