Hi Anchie, I am wearing a whole range of colours. Like you I still enjoy the old colours best, for me the Spring ones. I was never properly colour typed but was only in my 20s when I read the Colour Me Beautiful book by Carole Jackson and it was so clear that those colours were both what I liked and what I received the most compliments on. I have branched out into some cooler colours in recent years like teal, pewter, charcoal, light grey and purple. I feel quite good in these now with the grey hair, but sometimes I think they don't brighten my face, and I especially feel that with silver jewellery eg my silver chain versus my gold one.
Could you just experiment in some actual stores, like try on something nice in purple without buying, to get a sense of it on you?
And I agree that gold hardware is easier to find. I still prefer it anyway but my main handbag currently doesn't have very obvious hardware.
I do feel I have become more neutral and since I do like some cooler colours as well it is nice to feel I can wear them and hopefully look OK!
