On the 'seasons' thing, I'm definitely a 'warm' season. Make-up wise, I can't wear blue red lipstick or silvery/cool eyeshadows. I look much better in orange-reds, corals and straight up oranges on my lips, though peachy nudes are bad. I'm edging towards Autumn because of my sickliness in peachy nudes but I can't wear brown nudes on my lips either. I need a rosy nude with a tiny bit of warmth in it if I'm doing nude lips. Coppery and reddish burgundy colours look best on my eyes (mid-toned hazel with quite a lot of green).
Based on that knowledge, I try to only buy autumn type colours but I often fail at it when I see something I like that doesn't come in the 'right' colour. This is especially the case when the 'wrong' colour palettes and shapes are fashionable and finding anything right is really difficult. I end up panic buying something 'sort of right', because the shape is ok even though I know that the colour doesn't work. FGS.
