In short? Because of the @android:color part. This is to denote a color as defined by android. Hexadecimal colors are used everywhere. Here's a list of the colors defined by android https://developer.android.com/reference/android/graphics/Color.html

And here's the correct line:

android:background="#fff092b0"

Happy coding! :smiley:

I ran your code & it passed, but had to do it like three times.
