Australian colour consultant(顾问)Kylie Bartnicki is talking with a group of women in Pudong, Shanghai, who are interested in how colours affect people's confidence and help form(形成)people's first impressions(印象).

Kylie traces(追溯)back her interest in colours to when she went for her first job interview at age 18. "My mother bought me a new red top to wear to my interview and she said, "Wear this, and it will be lucky."' Kylie recalls. "I wore it, had a great interview and got the job. Ever since then I started thinking about how powerful the colour is, how it makes us look and how it makes us feel."

"When we wear clothes in a good colour, the colour will make our skin, hair and eyes shine and we look happy and smart," Kylie says.

Winter and summer are "cool colourings" and autumn and spring are "warm colourings". Someone who loves "cool colouring" might have red or golden hair, brown eyes and gold or yellow skin.

Chinese women belong to the "autumn season" if they have darker, peachy skin. Chinese women belong to the "winter season" if they have pale skin. Kylie says that Chinese women who have dark eyes and dark hair will look best in deep, rich colours. Light pinks and blues should be  avoided because they may wash our Chinese skin tones(肤色).

Their talk usually lasts one and a half to two hours and costs 600 yuan (89 dollars). Kylie says her customers(客户) are as young as five years old and as old as 90. The customers between their 30s and 50s always want some fresh ideas on developing their own personal style.
