People who suit cool colours generally have the following characteristics. When their hair goes grey it does so beautifully as a true salt and pepper, with no hint of ginger or yellow. They definitely do not have auburn hair, hazel eyes and freckly skin. Their skin is most likely to be alabaster white or olive. Their eyes have a dark rim round the iris or may be a very dark to mid brown.
People in this colour spectrum look truly terrible in any type of brown; rust, dull apricot and beige are nearly as bad.
Black, on the other hand, is a good colour on you and can be worn right up to your neck; it doesn't drain your face, like it does to people who suit warm or mid tone colours. Navy works too, but to wear it in a youthful way, make sure you team it with turquoise or emerald greens.
You look great in very strong purples. Grey is one of your main colours; don't think you have to be old and fuddy duddy to wear it - it will look chic rather than ageing. If your hair has already lost its youthful colour and is on the way to being white, grey is one of your best colours.
Icy pale colours work too, but make sure they are not teamed with black as it will take all the subtlety out of them.
