Humanity has five senses, and such senses help us to survive in the world by giving us feedback on on the three dimentions around us. We can get an awareness of all objects in our vicinity utilising a combination of inputs from touch, vision, taste, sound and smell. If we had no such inputs, we could not survive.

Even so, the flaw with being human is the method in which we interpret these signals - using our direct experience, we translate such inputs in an unobjective fashion. This means that sometimes we misread the actual surroundings that surround us. An example of this is colour blindness. If you see the colour red, it might in reality be orange. So how do we obtain the real colour of a thing without relying on our uncertain human senses? As this has been an age-old issue, there is already technology that exist to give a actual measurement of colour of a product.

Utilizing such a machine, it’s feasible to determine blemished merchandise for example. It could be faded print or impurities in food or in water, a colour measurement machine will notify you of anomalies at once by recording objective measurements of colour for every last item recorded. This is a great alternative to employing human quality control (for the only purpose of colour monitoring), and result in much more accurate feedback too.
