Spread a rainbow of happiness every time you switch on your table or pedestal fan by following this cool and easy to do idea. All you need to do is to remove the cover of an unplugged fan and paint each blade of the fan in the color of your choice. Preferably colors from the rainbow like red, blue, green, orange and yellow would be ideal as when you will switch on the fan, it will create a spectrum identical to that of the rainbow. Moreover, while choosing the paint keep in mind the material of the fan blades as there are different paints for plastic and metal. Happy painting!
