Interpretation of "The colourful life of Calum McCall"

This is a story of a man, called Calum Mccall, whose life is closely related to colours. It is so curious how he associates every situation that happens during his life with specific colours.
In his early years, he relates winter in Scotland with darkness. He also compares his relationship with his parents with a multicoloured rainbow. When he falls in love, he remembers all the colours from his childhood. After that, he gets married and has children. One of them points to the stars and looks in amazement. But Calum can not see anything so that night he can not sleep thinking about how he has lost his capacity to see.
Colours make reference to different periods of Calum McCal´s life. The loneliness of the streets, the immensity of the sky and the dissapointment of the people are represented in black. The discipline at school and at home are associated with the lack of colours. Love and children are related to the memory of colours in childhood.
Generally we tend to connect many events, situations, feelings and emotions of our life, with colours. Perhaps it is a way of keeping good times in memory and rewind those memories when we want.
