I'm a bit of both (in fact, as an earlier poster said, I change my mind a lot about what style I like, but broadly speaking there are two strands to my style).
Black, cream and various shades of light brown (honey/toffee/taupe) really suit my colouring, so I do wear them quite a lot - but I still want to be "different", so I look for interesting shapes, textures and sometimes bold prints or stripes. I never wear small jewellery (apart from wedding/engagement rings), partly because I think it's a bit boring and partly because I'm not physically a small person and the proportions would be all wrong. I love big, unusual necklaces and earrings, usually not both together, and I often wear lots of bangles together. mostly from charity shops.
But then other days I do wear lots of colour. I'm not quite the sort of person who'd mix a whole rainbow in one outfit (I admire those who do, but it's not quite me), but I like wearing a colourful print and then accentuating one or two of the colours with accessories. Favourite brights to wear are purple, orange, green, yellow.
I love slightly quirky brands of shoes like Art, FitFlop and Fly (and Ruby Shoo, but I wish they'd make more low heels), but have rarely owned any as they're a bit out of my price range! Hardly any of my clothes are expensive, and probably about half (I'd like it to be more) of the non-underwear items I wear regularly are second-hand. I customise things too, all in the hope of being "different". (I think I'm still making up for being unintentionally different at school 30+ years ago, by doing what I should have done then and defiantly cultivating a "different" look instead of being apologetic about not being able to afford the latest thing.) I love slightly quirky brands of shoes like Art, FitFlop and Fly (and Ruby Shoo, but I wish they'd make more low heels), although I have more conventional ones too, just because of the cost!
