I would like to analyse my own own colours as I can't afford a consultation. The season swatches are for sale on EBay but I can't decide if I am an Autumn or Spring. I tried an online test that said I couldn't be an Autumn as I have blue eyes and can't be a spring as I have brown hair! I'm definitely not a summer or winter. I find myself drawn to the Autumn colours.
I have mid brown hair with chestnut undertones, pale blue eyes with greeny yellow flecks. Pale skin that strangely tans easily and green veins.
If you do the fashion footprint thing on Dressipi then it gives you a set of colours they think might suit you best. I've not had my colours done but the set it suggests for me are certainly the ones I think I look best in It's free so might be worth a try before you buy anything?
I've had more than one autumn with blue eyes and more than one spring with brown hair (am an analyst). It just isn't possible to be accurate online, as QueenC says. Every online analysis ever makes me a winter and I am an autumn.
You can choose to limit your wardrobe to one particular palette or other for the sake of simplicity (which is worthwhile in itself! Makes life much easier), but there is absolutely no way of being sure whether it's 'right' or not.
