Colour has always been important to me. I recognised early in my life that there were some colours that I shouldn't wear. Not always for the most obvious reasons. One of these was orange during the Orange Walk (orange and turquoise were the seasons colours) ; another was green for similar reasons - at that time, when I was young, there was a lot of bigotry dressed up as football support; one team was green and white and Roman Catholic, the other was blue and Protestant. I was challenged on many occasions (what team do you support? - 'None' wasn't an acceptable answer) and attacked on one. I detest bigotry.
So far, using colour swatches from 7 Steps to Style, I have confirmed that I lie on the cool side rather than the warm side of the spectrum. I tend to suit silver and white gold jewellery rather than yellow gold, which isn't surprising when my hair is silver grey. My reds are blue reds rather than orange reds. Blues are pretty good. Blue allows green to be worn, though I don't like it - yellow greens are awful on me. Black, yellow and orange are virtual no-nos.
