One of the first qualities I identify when doing a colour analysis is whether someone is cool or warm in their undertone. This is a quality that many people find difficult to identify and it can lead them into making expensive mistakes when investing in clothes.
There are a couple of clues that could help you move in the right direction like skin behaviour in the sun, what metals suit best, but really, it is the precision dyed drapes that give an accurate result.
I demonstrate this in my latest video on Youtube. Get in touch if you are interested in an online or in-person analysis.
