Nervous suspects locked up in Britain's newest police station may feel relieved by a pleasant yellow color on the door . If they are close to confessing（供认）a crime , the blue on the wall might tip the balance .
Gwent Police have abandoned colors such as greys and browns of the 20th-century police cell（牢房）and have used color psychology to decorate them .
Ystrad Mynach station , which recently opened at a cost of ￡5 million has four cells with glass doors for prisoners who suffer from claustrophobia（幽闭恐怖症）. Designers have painted the frames yellow , which researchers say is a calming color . Other cells contain a royal blue line because psychologists believe that the color is likely to encourage truthfulness .
The station has 31 cells , including 12 with a “live scan” system for drunken or disturbed prisoners , which detects the rise and fall of their chest . An alarm alerts officers if a prisoner's breathing stops and carries on ringing until the door is opened .
Designers and psychologists have worked for years on color . Blue is said to suggest trust , efficiency , duty , logic , coolness , thinking and calm . It also suggests coldness and unfriendliness . It is thought that strong blues will stimulate clear thought and lighter , soft colors will calm the mind and aid concentration .
Yellow is linked with confidence , self-respect and friendliness get the color wrong and it could cause fear , depression and anxiety , but the right yellow can lift spirits and self-respect .
Ingrid Collins , a psychologist who specializes in the effects of color , said that color was an “ energy force ” . She said : “ Blue does enhance communication but I am not sure it would enhance truthful communication . ”
Yellow , she said , affected the mind . Red , on the other hand , should never be considered because it could increase aggression . Mrs. Collins praised the designers for using colors in the cells . Gwent is not the first British force to experiment with color to calm down or persuade prisoners to co-operate , In the 1990s Strathclyde Police used pink in cells based on research carried out by the US Navy .
