This is really a minor thing.
I just noticed that B4XViews for B4i doesn't support textcolor for buttons. But I suspect it could, if it would use the same logic as being used in ButtonSetAttributedText in the thread https://www.b4x.com/android/forum/threads/csbuilder-attributedstrings-builder.79153/ and also https://www.b4x.com/android/forum/threads/button-textcolor.47640/post-302295.
Like I said, a minor thing.
