I think the statusbar colors wrong well not wrong because it can be any you color you want but i think the default cololor is to dark, looking at this.

I see your using the correct primary color for the orange which is 500 but the statusbar should be 700 which is #E64A19

Like Google suggests here

Of course its your app and these are guidelines so its up to you if you follow them I just thought I’d mention this incase case you didn’t know.
