Hmm.
Today, I have been wearing trousers which are patterned with bright pink, bright red and purple. I get bored with grey/black/navy - and I wear quite a lot of red in particular, but other colours too, though usually more as a top than trousers.
They are noticeable, I admit - one colleague said they're great and should get award points (there's a recognition scheme for if you do a really good piece of work.) Another colleague commented on normal work attire, and he clearly considered these trousers as not part of normal work attire.
We tend not to wear formal work clothes unless we're meeting customers, and in my department and the nearby departments, that's a rare occurrence, so you see everything from jeans to suits. I really hadn't considered that these trousers might be seen as unsuitable in that context, yet he implied they were. I've worn plain red trousers quite often, so it's not a very radical departure for me. In fact, I think I've worm at least one red item every day this month - trousers or top, shoes, earrings, and tomorrow will be a red dress.
Now I am wondering that part of my choice not to wear makeup is because I don't really get what people's expectations and unspoken "rules" are. (Most of it is because as a teenager, I swam a lot, and I couldn't see the point of time-consuming regimes like make-up or fancy hair-dos if I was having to remove/reapply/sort it out at least twice a day, if not more.)
