Well first of all im sorry for my bad english ^_^.
Everyone love to know how they other feels or think, what they love and what they hate, its simple now if you know the color he/she love, well i can’t say you can him/her 100% but at least it will help you to get a general idea about this person, even about your self.
the almost colors i noticed people love them are:
White - brown - beige - yellow - orange - green - blue - purple - gray and black.
share the color you love and i’ll try to tell you what they means.
again this is not something accurate, sometimes it works, sometimes not, but it works fine almost the time .
