title: How do I find an element colour; the element I need to check changes colour when toggled
body: <p>I need to identify two colours from an element when it is toggled on and toggled off; for example when its On its rgb(40, 170, 228) and when toggled Off rgb(101, 113, 151). I am using Iwebdriver, so limited with the methods that this brings to the table. </p>
  
  <p>I have tried to not success <code>string colour = IWebElement.GetCssValue("background-color");</code> from another question, however, due to GetCSSValue not being present then I get an error </p>
