Dancergirl I had my colours done years ago - it was good but tbh it only told me the things I already knew - which is that bright, deep colours suit me and pale, pastel colours don't, mainly. I'm a Winter, so I suit navy, royal blue, deep red, burgundy, black, etc. If I have ever made the mistake of buying something in a pastel shade or beige, I just look ill.
I also have dark hair and brown eyes, but it also depends on your skin tone. I have olive skin, which is fair until the summer (what summer?!) when I tan really easily. Do you have a preference for jewellery colour? I don't wear much gold as it kind of clashes with my almost 'yellowy' skin - silver/platinum looks much better on me.
Also I remember being told your skin tone can be decided by looking at the veins on the inside of your wrist - if they look blue, you have a 'cool' skin tone (Winter or Summer) - if they look green, you have 'warm' skin (Spring and Autumn).
If that beige sweater suits you, you're probably an Autumn or Spring!
this is an interesting article, if you're not asleep by now...
