This toy thrills children as they see the world in different colours using an object beyond the human eye. The wide variety of filters excites them when they look at the world around them appear differently with each colour. This allows children to perceive colour as an abstract property or an adjective used to describe an object. This is the first time the child is able to grasp the complex aspect of colour being an abstract property as the objects they see take on the colour of the filter they are looking through.
