Any good app colors combination?

ASAP plz!

Going to need more info than that or you will just get random colours which is stupid.

A guy would suggest red and orange and a girl would say cardinal and tangrine.

Android? https://www.materialpalette.com

Black and lighter black plus accent for the dark theme, white and darker white plus accent for the light theme.

Make sure the accent is a perfect color.
Black can't be too black.
White can't be too white.
Lighter black must have the right amount of lightness.
Darker white must have the right amount of darkness.

Make sure to get the colors right otherwise some design freak will find you and kill you.
