What color did you notice first?
If the first color you noticed was one of these: Grey, Purple, Yellow.
you do not intimidate people easily, they usually find you comforting and nice at first sight!
If the first color you noticed was one of these: Blue, Brown, Green.
you may seem as if you are not the nicest and they will find you intimidating but when they actually get to know you they change their minds!
BUT if you see a mixture of both some people may find you nice and easy-going from the first interaction while some may find you a bit less approachable!
