Me!
I thought I was a Winter initally, then an Autumn. Turns out I am a Spring! Not a "definite" blue spring (Spring into Winter) but she did mention the "blue" factor but was reluctant to give me an exact spring category.
My absolute best colours are Coral/Flamingo Pink/Bubblegum pink (shades of orangy pinky coral basically, but bright not pastelly), a bright "kerry" green, (like mega-green grass I guess, not to bluey), "Oxford" blue, "bright" navy, bright slightly orangey red (geranium) and "Poppy" which is a true red but on the slightly warmish side of red, and "aquamarine" like a really bright turquoise, turqouise was also one, and to a lesser extent aqua (which I guess is lighter still, really). I can also do buttercup or brightish yellow, but not "as good", and cream, oatmeal, and some other neutrals which are fine but not my best colours. And a warm (almost "golden") chocolate brown (not too dark).
I got it wrong due to being natrually brunette (though not dark brown) and what I thought were dark brown eyes which were actually "bright" brown eyes (in as much as brown eyes can be bright). Its also down to the "high contrast" of my eyes and eyes against skin and hair etc etc.
So I misdiagnosed myself by basically mistaking deep for bright or high contrast and being biased about the warm/cool thing and what I thought suited.
