Jitsi Meet Mobile App Change In App UI Color from Blue to other

Hello,

I am looking to change the UI color of Jitsi Meet app from blue to some other color. I did it about an year back but i dont remember which file i had changed the color from.

I am using files from latest Master branch and was able to change the dialog box color from ColorPalette.js file but cannot find an option to change Header and Footer blue color.

Experts please guide.
