Colours of day

Has anyone ever said to you "you can't wear those colours together!". In Northern Ireland we might say "did you dress in the dark today?"
Any way we hear it, it presumes there are coherent enforceable fashion laws with watchful fashion police out to catch those of us who might be..... More experimental in clothing choice.
Well, try saying that to nature who regularly puts together bizarre colours such as this snap!
So be led by one who knows!
