Many people feel a sense of loneliness at some time during their life. This is a painful feeling but not a destructive one as this feeling comes from our soul's desire to go home and be united with the divine. We must remember that we are given everything we need for our time here and the situations we find ourselves in are given to us as lessons, so we can grow and become self-conscious, to really know ourselves. 
People colour other people's lives. We are attracted to people whose colours are in harmony with our own. Thus blue people will get on very well with green and violet personalities, but will clash with the reds and oranges. This is because the blue person likes peace and solitude while the orange person loves people, noise and parties. Ask your partner, friends and colleagues what their favourite colour is and find out about their colour personality. 
Many people are attracted to people whose colour energy they need at that time. Once they have drained that energy off that person they move on and that relationship or friendship will come to an end. At some time or other, we have probably all experienced that feeling of being sapped of our energy by another person. 
Although we may have a bias to one particular colour, a mature adult needs a balance of all the colours in his or her Aura. It is only when we have a balance of all these colour energies and our chakra centres relating to these colours are open, that we can begin to have whole and lasting relationships.
