Hi Jilleanne,
When I first transitioned at work, my company (paid!) for me to see a beauty consultant. Two days was great and one of the things I had done, was colour matching (excuse the English spelling), which used a computer programme to analyse skin tone, eyes, hair etc.
The next step was to drape certain colurs across my shoulders and to look at the effect and to see how I felt about them. We also did this with glasses (frames) and make up.
To cut a very long story short.... yes there are seasons (Spring, Autumn, Summer and Winter) and also various sub-categories (I am soft Autumn for instance).
But I know what colour and tone of make up suits my skin, hair tone and I have a colour swatch, that I use to select some of the clothes I wear.
I never liked browns or greens, but they actually look very good on me and I can actually wear pink!... errr something I never wore as a guy!
The two days cost about $200 US and really gave me an insight into colours and their effect.

PS... Changed my nail polish on my toes yesterday to an orange colour because its Summer!
