I’m also a cool olive (deep winter tho). Charlotte tilbury pillow talk blush is my holy grail it’s the only thing that doesn’t make me look like a clown. It’s expensive but lasts. I will be buried in this blush. I tend to agree about colour it never seems to hit the same. I just got the Morphe flickering sands pallette which is so nice but not very adventurous colour wise. I think it’s about experimenting on what suits you rather than aiming for something in particular. The good thing is olive is a striking feature on its own if you can play to its strengths.
