Tried doing custom skins, seems like it turned out decent..

– I made the buttons darker so there’s not a lot of contrast between that and the UI’s background (and the original one looks pretty ugly, to be honest).
– Completely de-saturate most of the things that have some blue-ish tint to it (again, original looks pretty bad to me).
– Maybe changed the blue-red’s shading. Not a fan of how the blue turned out, and the red is not too strong now.
– And then the “Red” (Cyan if you’re using dark mode) was changed to look like the blue buttons.

Oh ye, I have to dig out the apk file just to assemble the template.
