Colours are the frequencies of the light emitted by an object, enabling two otherwise identical objects to be distinguished at a distance, in a similar way to two different musical notes. Red is the equivalent of a low pitched note and violet, high. Looking at a picture can be like listening to a song (a wide range of frequencies and textures), evoking emotions or stirring memories.
Just off the top of my head
You haven't described what a colour looks like. Sorry pal.
