@damontecres Nice additions! I especially really like brown (coffee, mocha, etc) as an option for a dark theme that is usually either blue, grey or black on Android apps! I see no weird inconsistencies or contrast issues so this is almost good to go, but I have one nitpick; the playback buttons, when selected, have a kind of sickly, yellow-hue brown? I don't mean to be gross but it's a bit too "poopy brown" rather than an earthy, natural, pleasing to the eye brown so if you can make it a tad darker and maybe reddish instead of yellowish, it would look better? In other words, just avoid that shade and go with shades that look more robust and autumnal? Maybe something like https://www.figma.com/colors/mocha/?

I hope I'm not being too nitpicky with this. The "red" theme buttons on the video player look great and have a nice brilliant tone to them but when you see them side by side with the "brown" buttons, they make the "brown" buttons look a bit anemic, lacking in color, etc. A more robust replacement to that shade of brown would really spice things up, so to speak.

Yes, I agree. I've updated the color and updated the image in the PR body. I used the mocha color you suggested and I think it looks good
