Munisri and Jaina 68 have referred Optical Society, 1922 to define colour as sensation produced through light and eye from the activity of retina and its attached nervous mechanisms. It is an objective natural property depending upon structural specificities. Accordingly, the colour has two types - (i) perceived by the eye and (ii) objective. If there is no sense of sight, how the colour could be perceived ? Thus, the objectiveness of the colour becomes important. Each object must have its own colour visible to our eye. Many scientists and philosophers, however, agree to colour as only to be subjective. In contrast, Muniśrite has described two factors responsible for colour sensation - (i) subject and (ii) object. If 'a' is the objective property, b, b, etc. are subjective properties and k, k, are perceived colours, the colour sensation will be similar to all subjects, their senses being normal, or
If b = b, k, = k, or a + b = a+b = k, = k = k
This suggests that for normal colour sensation, the two factors must be normal and undistorted. If the factors are faulty, the sensations may also be similar. Thus, the nature of the object is also important for colour sensation. The supra-sensuals have a different case, however.
