HOC, in person, all the way here.
I have brown hair and brown eyes and many would think Autumn. When I asked my mum (good old mum) she said I looked best in bright colours. I was very confused. My mum is deep autumn so maybe psychologically I thought I should be too.
Anyway in person it became clear I was Spring. Autumn muted colours looked heavy and serious and made my face more square with shaded lines. In Spring colours my face was more oval and smooth (you get into this level of detail and navel gazing in person 😂).
Not just any Spring, Paintbox Spring which is the brightest and most saturated of all the palettes. My eyes are bright and my hair colour is strong so it can take it. I would never have seen it myself and doing it online I didn't quite have the confidence. When you do it in person and trust the person you can see it yourself. You won't agree on every colour, she loved me in purple and man I find that colour hard to wear, although I do agree it's good, I just have negative associations of it.
I did have a minor existential crisis afterwards, but they give you a colour palette with useful tips. I now just mainly buy my top 9-10 colours. They tell you what % a colour looks good, e.g. light pink 25% so like a scarf, or bright navy 100% so wear it at any proportion from a scarf to a full dress. It makes shopping such a doddle as I can discount 75% of things and my whole wardrobe matches. I'm not super strict, I do wear black as its the corporate colour but not near my face etc.
