Ahh the MaterialTheme confused me along w the initial color of buttons looking like a new activity I added that did use material colors It seemed that MaterialTheme initially picked up the colorPrimary etc colors from the usual R colors file slightly smiling face That tutorial shows you how to override this but I guess the question why not just make the default pick up the standard old theming colors

Wait on that codelab screen it says We provided our custom colors overriding those from `ColorPalette` which default colors to the Material baseline theme unless otherwise provided This implies it grabs the default unless it means the default when you create an app in Android Studio which is what is seems to be doing

That doc is also out of date ColorPalette has been renamed to MaterialColors in case anyone else is looking for it man facepalming

And default just means the colours defined in the Material baseline theme <https material io design color the color system html color theme creation>

Oops was using ``` def compose version = 0 1 0 dev02 ``` because android studio didn t flag that it was old time to hook in the usual benmanes plugin disappointed The material baseline theme makes sense would be nice if the codelab linked to it so we wouldn t think it links to the usual Android app s theming system which we honestly should have some way of doing if we re supposed to fold Compose in slowly into an existing app IMHO

We ve been thinking about integration with MDC library s theme it s much harder to integrate with platform AppCompat themes because they don t really match the newer Material spec for colors There are lots of colors that just don t exist in platform themes so even best case you would still need to go and add colors yourself which might be more confusing than just not inferring anything from the theme
