     Nervous suspects (嫌疑犯) 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 a crime (招供), the blue on the wall

might tip the balance.

     Gwent Police have stopped using 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 (improve) 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 and persuade prisoners to co-operate. In

the 1990s Strathclyde Police used pink in cells based on research carried out by the US Navy.
