Mind Reader - Think Of A Colour

Sometimes when I’m mind reading, I ask a person to think of a colour. Most of the time I will ask the person to think of the first colour that comes to mind. Over 95% of the time I get it right and entertain the person thoroughly. But 5% of the time the person is so bent on proving me wrong that they will think of a colour with an ultra-specific name…as in this example…if you are such a person, you may have control issues…just saying!
