Bug: Changing PrimaryColor to CustomColor1 Causes Build to fail

Thank you for developing this amazing tool.

I decided to use my CustomColors as a kind of color pallette. I set PrimaryColor to CustomColor1, and it showed the correct color to the right. But then when I tried to build my app, I got this:

BUILD FAILED:
The signed apk was not built successfully. This could be due to an internet connection problem. On the first build, the compiler needs to connect to the internet to download some library files.

When I switched it to a normal color code, everything started working again.

Perhaps RAB and SAB could either be adjusted to allow for this use case? Or, show the user an error dialogue when he tries to do something like this.

Thanks!
