Can’t Convert error to color: type=0x2

Question

In Xamarin, when debugging the application, this error appears

Can’t Convert to color: type=0x2

in the method SetSupportActionBar(...);

Excerpt:

Android.Support.V7.Widget.Toolbar myToolbar = FindViewById<Android.Support.V7.Widget.Toolbar>(Resource.Id.toolbar);
try
{
    SetSupportActionBar(myToolbar);

}
catch (Exception ex)
