If you've been analysed tonally, your dominant colouring is cool with no warmth to it. To achieve harmony and balance, you need to wear colours which have blue or cool undertones and which are of medium to deep depth. You will need some contrast between colours to enhance your look. Avoid yellow and golden based colours.
Cool + Soft/Light = Summer
Cool + Clear/Deep = Winter
You can find more detailed information about the two systems, in this blog post.
