Mat color changes based on temperature. For example, mat is warm (right out of your hot mail box) you place your warm hand onto the mat, it will most likely NOT react as there is very little difference in temperature between the mat and your hand. It is important that you allow your mat to cool off right after you have opened it. If you are just too excited and cannot wait for it to cool off, drip cold water or let ice melt onto it or place it in the freezer for a moment. Watch your mat react. Color is darkest when mat is cold and color is lightest when mat is warm. It is not recommended you use in outside (when it is hot) nor at room temperature, you will most likely NOT get a reaction. Picture demonstrates cold mat, in a cool a/c filled room, against warm hand.
