I don't know how to get the colors hexes from the installed app on my Shield though.
If i could run the app on PC where one can use a tool like that like to pick colors from images or the desktop screen....but there is no way to do that,.
And my monitor will have skewed values since it has its own color/bright/contrast settings tweaked.
here is the apk file I am using: LINK
I suggest you can install that version on your test device and use a color picker or decomplie the apk whatever it is you do, and get the values that way. or just try to match it by eye. idk.
If that does not help you, then...i was not intending to have to detail out every single color code to make a "custom" version. That is more time and effort than i have to give at the moment. Like I said, the previous look is what I would want. But, I am fine using the aforementioned apk version for the foreseeable future.
Not sure how advanced a programmer you are or if it as simple as just changing preset global or local variables in the apk files....
But perhaps, you could make a program of your own, a app tweaker that would make it so that a user could just select the colors they want for each GUI aspect of the app, u input it the apk file and it makes the modded apk file.
Maybe its not that simple. Idk. just thinking aloud.
It has bene a long time since i have dealt with code, back in the COBOL and plain C days of code.
