What Colour Is Your Soul?

'Can you paint with all the colours of the wind?'. That is a line from one of the first songs I ever sang and it is a song that I now love to teach my singing students. The reason I ask this question is because I have been thinking a great deal about the seasons and the colours they bring with them. 
As a young singer I competed in many singing competitions and my Dad was always fascinated at how the adjudicators would describe the 'colour' of a singer's voice. My own voice was often described as being 'gold', 'chocolate', 'bronze' and 'dark'. These types of colours are used to describe a warm, often low, voice in singing. Words like 'bright', 'yellow' and 'light' are then used when we talk about a higher voice. I am wondering if there might be a connection between the colour of our souls and the colours that we are drawn to. 
I always say that I love the  Autumn and Winter. I love the colours and the cosyness of these seasons. Most people can't understand why I don’t love the Summer but maybe it is because I don’t relate to that season's colours. 
I wonder if other types of artists feel this way. Does your brush often hold a certain colour? Do you base a lot of the stories you write during a specific season? What is your favourite colour? What colour is your soul?
