Visual Studio 2012 complains about comparing two Brushes

Question

Visual Studio 2012 complains about comparing two Brushes:

private void SetLabel(string stText, Brushes colorBackground)
{
  if (colorBackGround == Brushes.Yellow)
 ...
}

Error message: "The name 'colorBackGround' does not exist in the current context"

Answer 1

colorBackGround is not the same as colorBackground! C# is case sensitive
